Emilie De Ravin Welcomes Baby Girl With Boyfriend Eric Bilitch

Best news of the week: Emilie de Ravin, aka Claire Littleton from "Lost," welcomed a baby in real life. 

The actress took to Twitter on Sunday to share the happy news , announcing that she and her boyfriend, Eric Bilitch, welcomed a baby girl named Vera Audrey de Ravin-Bilitch. 

Bilitch took to Twitter, as well, writing a sweet note about de Ravin. 

We, of course, know and love de Ravin from the ABC drama, which ended in 2010 after six confusingly-addictive seasons. Her character, Claire, was the pregnant crash survivor of Oceanic Flight 815 who delivers baby boy, Aaron, on the island. Although she mysteriously disappeared in Season 4 , Claire returned as a series regular in Season 6. (And that's all we'll say about that.) 

Now back to de Ravin -- this is her first child. She currently stars as Belle French on "Once Upon a Time."   

Congrats, Claire Emilie!
