Kate Hudson is getting some quality time in Boston with all three of the men in her life: son Ryder, boyfriend Dax Shepard and ex-husband Chris Robinson.

Kate and Ryder have split time between his dad and her new beau. On Wednesday, the 3-year-old was perched on the shoulders of the Black Crowes frontman, and on Thursday it was Shepard who took Ryder for a ride.

Ryder also visited his dad when the Black Crowes played a show in Hyannis, Mass., the Boston Herald reports.

Hudson, 28, told Harper's Bazaar recently that maintaining her relationship with Robinson was key. "For both Chris and me, our main focus is, and was, Ryder. And happy parents, happy baby," she says. "Therefore, I love Chris to pieces."

The actress is in town filming her new movie Bachelor No. 2 with Dane Cook, Jason Biggs and Boston Celtics star Ray Allen. The group has been making the rounds – attending a recent L.A. Galaxy/New England Revolution soccer game and a Justin Timberlake concert.

As for Hudson and Shepard, 32, the pair started stepping out together in L.A. in July.

Motherhood, however, has changed her romantic life. "Dating becomes very different," she told Harper's. "You realize after you have had children that you'll never love anything more than your child. ... So it makes the new sort of single-mom dating process very different. It's like growing up. It's adult."
