Robin Thicke and his girlfriend April Love Geary are expecting a baby!

The 40-year-old singer has been dating the 22 year old ever since he and wife Paula Patton filed for divorce three years ago. Geary is 3 months pregnant and made the announcement via Instagram on Thursday.

“Robin and I are very excited to share with you all that we’re having a baby! The due date is March 1st, Alan’s birthday!” she captioned a picture of her latest sonogram.

Thicke and Patton are still technically married as their divorce isn’t yet final, and they’ve been engaged in a bitter custody battle over their 7-year-old son Julian. According to TMZ, the singer is expecting a girl with Geary, as a source close to the couple confirmed that Thicke’s son is “super excited for a little sister.”

Their due date, March 1, would have been Thicke’s late father’s 70 bithday.
