Hayden Christensen @ Rachel Bilson's House

Hayden Christensen pays a visit to gal pal Rachel Bilson‘s home in Los Angeles on Tuesday.

Hayden and Rachel (both 26) will be heating up silver screens across the country next month when their new movie Jumper opens on Valentine’s Day.

In the meantime, watch out for “Donate It: Jeans for Homeless” ads featuring Hayden and Rachel. Nonprofit teen organization Do Something and Aéropostale stores launched Teens for Jeans, a campaign encouraging people to drop off any brand of used jeans at Aéropostale stores in exchange for 20 percent off a new pair. Jeans will be donated to the City Gospel Mission and Bethany House Services.
