Call off the bump watch!
Rachel Bilson and fiance Hayden Christensen aren't expecting a baby.
Do you think these stars are pregnant? They're denying!
After the actress, 28, was spotted heading into a doctor's office over the weekend with an oversized rain jacket, blogs speculated the former O.C. star was hiding a bump. Of those reports, her rep tells UsMagazine.com there's "absolutely no truth to Rachel being pregnant."
Bilson and Christensen, 28, announced their engagement in February 2009. The two co-starred in 2008 action flick Jumper.
