"Hayden is totally pregnant!" an inside source tells the mag.

According to Us, Hayden and Wladimir have been dating since 2009, when they met at a book party. They broke up for a while in 2011, got back together and became engaged in spring 2013.

I'll keep you posted on any updates or confirmation. Keeping an eye on Hayden's Twitter feed... Nothing there yet!

P.S. I was on my way back from Naples—we saw dolphins (Hayden is a serious dolphin activist)!—when I heard this fun news, and I had to share, of course, before hitting the warm ocean here in Marco Beach, Florida. I'll update our Who's Pregnant in Hollywood gallery ASAP later. See you there!
