'I'm ready,' said Big Little Lies star Reese who managed to appear very glamorous in a turquoise fuzzy coat with her sun-blocking glasses on.

'If you have your glasses… get out outside now!!' wrote the Sinner star whose husband Justin Timberlake hit the like button.

And Osbourne was chic in a leopard print top and capri leggings as she posed with her glasses on by her swimming pool with partner Sid Wilson who had a Princess Diana shirt on.

Model Shayk - who dates Tom Brady - shared a look at her glasses as she held them against her black crocodile Hermes Birkin purse. 'Ready,' the Russian-born star wrote over her photo. Irina, the ex of Bradley Cooper, also put the eclipse glasses on her black dog.

Jessica Alba had a lot to say. 'Honoring and feeling into this Solar Eclipse ✨,' began the Sin City actress.

'Eclipses are all about new beginnings but this one has such an element of closure - about letting go so you can walk through a new portal and move into your power.

'This eclipse is in Aries ♈️ which is about our souls purpose - our life’s mission - so it really invites you to release anything that blocks you from aligning with you true soul fulfillment,' said the Honest Company mogul.

'It is about understanding that your pure soul - your essence - is worthy of love and acceptance no matter what. Everything that makes you dynamic, that isn’t easy, that can be perceived as a flaw or a shadow side of you… it’s all about encompassing the darkness with the light. We’re here to have this very human experience for a reason.'

The wife of Cash Warren ended with: 'Wherever you are, whether you may be able to see the eclipse or not, it will be felt energetically around the world - so I hope you take a moment to connect, fill yourself with love, meditate with the energy, let go of what no longer serves you…'

The pal of Jennifer Lopez added that the 'vibration' that’s being created right now will last about two weeks, so there is time to work with the energy.

'Take time to reflect, go in, sit with yourself - and just ask yourself what doesn’t belong to you? It’s time to align with you - and chose YOU. Who are you and what do YOU want? What is your soul here to do and manifest? Sending so much love and light ❤️.'

Jamie Lee Curtis, who is doing a Freaky Friday sequel with Lindsay Lohan, said, 'Praying the eclipse can reset the world to one at peace!' 

The solar eclipse has reached totality for the first time, as the moon completely blocks the sun in Mexico and continues to move towards the United States.

The Mexican beachside resort town of Mazatlán was the first major viewing spot to be plunged into darkness from the celestial phenomenon.

The total eclipse became visible around 11:07 AM MT and was present for 4 minutes and 17 seconds, according to NASA.

Thousands of people gathered along the coastal promenade, setting themselves up in deck chairs with eclipse glasses as an orchestra played the 'Star Wars' theme.

In Kerrville, Texas the first partial eclipse became visible in the United States around 12:59 PM CT and is said to become a total eclipse around 1:32 PM CT.

Thousands have packed towns along the total solar eclipse 'path of totality' where the moon will completely block the sun, starting in Mexico and moving through Texas where it will travel up to New England and finish in Canada.

In any one location along the path of totality, people will see a partial eclipse followed by the total eclipse, and then a partial eclipse again.

Although newly announced forecasts for Monday are ominous, suggesting thunderstorms and cloud coverage that could limit visibility, deep-pocketed thrill-seekers are undiscouraged.

The Lone Star State will be the first state to see the celestial event around 1:27 PM ET, then Oklahoma is next at around 1:45pm CT, followed by Arkansas at 1:51pm ET and Missouri about five minutes after.

Illinois is next in line along the path of totality, with Carbondale experiencing the solar eclipse at around 1:59pm CT and Paducah, Kentucky about one minute later.

And Evansville, Indiana at 2:02CT and then Ohio is expected to witness it at around 3:13pm ET.

State officials have estimated that up to 556,000 people will be visiting the Buckeye state.

Erie, Pennsylvania is next, with the solar eclipse set for 3:16pm ET, followed by Buffalo, New York at around 3:18pm ET.

The path will continue up north, reaching Burlington, Vermont at 3:26pm ET, Lancaster, New Hampshire at 3:27pm ET and Caribou, Maine at 3:32pm ET.

Tourists who traveled thousands of miles to catch a glimpse of the solar eclipse in Dallas - what was meant to offer the best view - are racing elsewhere as storm clouds gather over the Lone Star state.

Although Texas has one of the best geographical positions to view the once-in-a-lifetime celestial event, clouds started to roll in around 9 AM local time as severe storms are expected Monday night.

Forecasters in Forth Worth explained the morning cloud cover would start to break up around noon, allowing many to enjoy the spectacle in the sky.

The National Weather service forecasts that Northern New England will the best location for clear viewing of the total solar eclipse Monday afternoon.

Forecasters said Southern Texas will have an increase of cloud coverage prior to the arrival of the solar eclipse.

NASA's Eclipse Soundscapes Project will use thousands of volunteers throughout the U.S. to help collect data form Monday's celestial sensation.

Nearly, 2,500 people have signed up to fill out written multisensory reports on animal behaviors and human reactions throughout the event.

In Niagara Falls, photographers lined up early in the morning to snag the best spot to get pictures of the eclipse.

Astrophotographer Stan Honda told CNN photographers of any skill level can capture photos of the eclipse as long as they have a sturdy, steady tripod and a remote shutter release for your camera.

'With pretty much any kind of camera or any lens, you can get a good picture of the eclipse,' he said. 'I would just recommend a fairly sturdy tripod, to make your setup pretty steady, and a remote shutter release, because that allows you to take the pictures without jarring or moving the camera too much.'

'A safe solar filter really is a necessity for the partial phases, and the American Astronomical Society has a whole section on its website about solar eclipse glasses and filters that they approve as being safe to use.'
