New Couple Alert: Cisco Adler, Lydia Hearst-Shaw

Cisco Adler is more than just a dude who plays in a band and has giant balls. He's a dude who plays in a band, has giant balls and dates rich girls.

His new high-profile gal: model and publishing heiress Lydia Hearst-Shaw.

Adler, 29, lead singer for the band Whitestarr, split with Mischa Barton in February, and was previously engaged to Kimberly Stewart. There was also the pic of Cisco Adler naked found in Paris Hilton's locker.

Lately, though, he's been all over town with Lydia Hearst-Shaw, 23. The two attended The Cinema Society's screening of We Own the Night on October 9.

Lydia Hearst-Shaw and Cisco Adler, a hot new couple, were seen the following night sucking face in a private booth at New York's hot nightclub The Box.

They were together again Thursday at Tenjune, where Adler was a guest DJ.

Hearst-Shaw, who recently ended a long-term relationship with Justin Bertha, the sidekick of Nicolas Cage in National Treasure, is the face of Nars cosmetics - and the great-granddaughter of publishing magnate William Randolph Hearst.

"Yes, it is true that Cisco and Lydia have been seen together recently," says Lydia Hearst-Shaw publicist Alan Rish. "But I don't think this is serious. It is very new."

Is it as serious as the new relationship between Cisco Adler's bandmate, Alex "Orbi" Orbison, and LA Ink tattoo artist celebrity Kat Von D? We'll find out.
