Lauren Sanchez flashes her stomach in a crop top while enjoying a stroll with her fiancé Jeff Bezos in Miami

Amazon founder Jeff Bezos and his fiancée, Lauren Sanchez, were the picture of love while out and about in their new home city of Miami on President's Day.

The couple was spotted grabbing coffees and walking around the Coconut Grove Art Festival, an annual event that helps fund year-round arts programs.

Sanchez, 54, flashed her stomach in a white crop top and army green cargo pants as she strolled arm-in-arm with Bezos, who celebrated his 60th birthday last month. 

The former news anchor topped off her casual look with a cropped denim jacket, chunky brown boots, and aviator sunglasses.

She was beaming as she chatted with her husband-to-be, and her massive diamond engagement ring was on display as she held her coffee cup in her left hand.

Sanchez's long raven hair was tucked behind her ears, revealing her large diamond studs, and she had on natural-looking makeup for the neighborhood outing.

Bezos was also dressed casually in a navy crewneck T-shirt and light denim jeans, which he paired with a plain blue baseball cap, white sneakers, and round shades.

The couple appeared to be deep in conversation, and at one point, Sanchez was seen sticking her tongue out and making a face to the billionaire's amusement. 

Bezos announced in November that he and Sanchez were moving from Seattle to Miami to be closer to his parents. 

'I've lived in Seattle longer than I've lived anywhere else and have so many amazing memories here,' he wrote on Instagram. 'As exciting as the move is, it's an emotional decision for me. Seattle, you will always have a piece of my heart.' 

Bezos bought not one but two neighboring properties on Indian Creek, an exclusive island off the coast of Miami, for a total of nearly $150 million this year. 

Retired NFL star Tom Brady, former first daughter Ivanka Trump, and singer Julio Iglesias also called the exclusive community known as 'Billionaire Bunker' home. 

The couple's outing comes a week after Sanchez paid tribute to her son Nikko Gonzalez with a gushing Instagram post in celebration of his 23rd birthday on February 12.

The proud mom shared throwback photos of her oldest child when he was a toddler, as well as more recent pictures of the model, who made his runway debut last month.

'Happy birthday Nikko. I love you SO much,' she wrote in the caption. 

Sanchez had kicked off Nikko's birthday celebrations a few days early with a pizza dinner on February 9, which she also documented on Instagram. 

She shared a photo of herself sitting across from her son at the restaurant, writing: 'Happy early [birthday] @nikkogz. Loved our day together. Eres mi mundo [You're my world].'

Sanchez also has a younger son, Evan Whitesell, 17, and a daughter, Eleanor Whitesell, 16, with her ex-husband, Patrick Whitesell.

Whitesell, the executive chairman of the entertainment agency Endeavor, was reportedly the one who introduced her to Bezos.

Last week, Sanchez paid tribute to her son Nikko Gonzalez on Instagram in celebration of his 23rd birthday on February 12. They enjoyed a pizza dinner together a few days before

It's unclear when Sanchez and Bezos started dating, but their romance was first exposed by the National Enquirer in January 2019, while they were both married to other people.

Soon after, the Bezos divorced Mackenzie Scott, his wife of more than 25 years and the mother of his four children, while Sanchez left Whitesell. 

They made their first public appearance together in May of that year, and four years later, they got engaged in May 2023. 

The bride-to-be opened up about the moment Bezos asked her to marry him in an interview featured in the November issue of Vogue.

She recalled how he popped the question on his yacht after they enjoyed a romantic dinner under the stars together.

Bezos hid the pink diamond engagement ring under her pillow, and she admitted that she almost 'blacked out' when she saw it. 

Sanchez said they were in the early stages of planning their nuptials, noting that she was more focused on the billionaire's 60th birthday party at the time. 

'We're still thinking about the wedding and what it's going to be. Is it going to be big? Is it going to be overseas? We don't know yet,' she explained.
