HOLLYWOOD - Kate Hudson's ex-boyfriend Dax Shepard has already found himself a hot new blonde just weeks after splitting from the Almost Famous star.

The actor, 32, was spotted flirting with Heroes star Kristen Bell at the grand opening of Planet Hollywood's Koi in Las Vegas, and then they showed up together at Tao's second anniversary party a day later.

An eyewitness tells In Touch Weekly magazine, "They were holding hands and having fun with friends. They were dancing and then left together."

The couple was then spotted at a Maroon 5 concert at the Palms' Pearl Theater.

Meanwhile, Shepard's ex, Hudson, has been romantically linked to both Orlando Bloom and newly-single Heath Ledger.
