That's right, these beautiful stars have recently announced that they're gonna be starting up their families and the world couldn't be more thrilled about it.  I'm sure these lovely ladies are going to make great mothers.  And let's not forget about the men behind these women and their budding bumps.  

Mila Kunis (30) first met her fiancé, Ashton Kutcher (36) when they were just teenagers staring on That '70s Show playing love interests Jackie and Kelso.  The two rekindled their friendship back in 2011 after Kutcher and his then wife, Demi Moore, announced the end of their six year marriage. 

Rachel Bilson (32) sparked a flame with her leading man Hayden Christensen (33) when the two starred in Jumper back in 2008.  

Let's not forget about the most recent Hollywood starlet that announced her own pregnancy, Hayden Panettiere.  Panettiere (24) is not only pregnant, but she's also engaged to Ukrainian heavyweight professional boxer Wladimir Klitschko (38). 

One thing is for sure, all the best wishes go out to these beautiful women, their men, and their babies!
