Jaime told US Weekly that her and boyfriend, Hamzi were experiencing difficulties trying to conceive. 'We thought we were going to have to do IVF,'she explained at the time.
After suspecting she may be pregnant, the star admitted to US weekly: 'I went and got a Clearblue test and then had Hamzi go back to the store and get about five more because I was like, "Oh, my God!".'
Her partner will be a first-time dad and Jaime told Us: 'He's gonna be such a good dad. We're excited. [Twins] have a built-in buddy. I'm really excited about that part.'
Congratulations to the lovely couple!
