The lifelong bachelor, 42, a onetime beau of Sandra Bullock's and Jennifer Aniston's, plans to run the New York City Marathon Nov. 6 and attend a six-hour preparatory marriage counseling session the next day.
"Hopefully I can do it in a hot tub," jokes the actor, who currently appears in George Clooney's Good Night, and Good Luck.
Meanwile, Tate's TV daughter, Mischa Barton, 19, has a new romance of her own brewing with 27-year-old singer Cisco Adler of the L.A. rock outfit Whitestarr.
Barton, who broke up with oil heir Brandon Davis in July, and Adler, whose failed engagement to Rod Stewart’s daughter Kimberly reportedly resulted in her altering a tattoo from "Daddy’s Little Girl Loves Cisco" to "Daddy’s Little Girl Loves Disco," have been spotted dining around L.A.
"She's really happy," says a source close to Barton. "They're taking it one day at a time, but they're together and having fun."
