Justin Bartha & Joshua Jackson Play Poolside With January Jones' Baby Boy (PHOTOS)
Both The Hangover actor, 33, and Dawson's Creek star, 33, played in the pool with the baby boy, who was dressed in a pair of adorable swimtrunks. Meanwhile, Mad Men beauty January just dipped her legs in the water and shielded the sun with a hat and sundress.
The celebrity crew, which also included one of January's gal pals and an adorable pooch, were all smiles as they played with the baby.
January, who has yet to reveal the father of Xander, has opened up about being a new mom.
“I am enjoying [motherhood.] I adore it,” she told Access Hollywood this past March. “[Xander] is awesome.”
