'I can't wait to meet her!! I've always wanted to be an uncle!! So happy for you!! Congratulations.'

Jordan and his girlfriend, who have been dating since 2020, previously announced they were expecting a baby together on January 21 with adorable snaps from a pregnancy shoot with ultrasound images.

On Mother's Day, Jordan also posted more snaps from their shoot as he shared a gushing tribute to his partner.  

'Happy Mother's Day to the most beautiful momma in the world,' he penned to Weeks. 'To the woman that not only made me a daddy but pushes me to do better each and everyday. I'm blessed beyond measure. I love you Jenna!'

In March, CBS announced the new comedy series, starring Montana Jordan and Emily Osment, will be replacing Young Sheldon's time slot in the fall.
