Life's a party for Jennifer Aniston!
So which fellow celeb's beachy bash did the couple attend?
They helped Christine Taylor, wife of Ben Stiller, ring in her 40th birthday—and by the looks of the bag Justin is carrying, he and Jen came bearing gifts.
The low-key bash was held on the island of Kauai, where Christine and Ben have a vacation home.
Justin is turning 40 himself on Aug. 10. Wonder if he and Jen will celebrate in Hawaii or if she'll throw him a party in her new West Village apartment back in the Big Apple?
