Hayden Christensen And Rachel Bilson, Definitely Back On!

We knew it!

Last week, Hayden Christensen was spotted leaving former fiancee Rachel Bilson‘s house in Los Feliz, which could only mean one of two things: they had either reconciled, or were having furious ex-sex!

Well, sources are confirming that it was the FORMER!

An insider reveals:

“They’re dating again.”

Glad to see they’re taking it a little slow and not jumping right into the engagement again!

Best of luck, guys!
