Samantha Ronson Disses Aubrey O’Day?

Aubrey O’Day was reportedly on the prowl in Las Vegas, but newly single Samantha Ronson wasn’t interesed in Aubrey’s advances. While SamRo was DJing at the Nascar Champion’s Party at Club Lavo, the Danity Kane singer reportedly jumped up on a banquette directly in front of her to try to get her attention.

“She was doing everything to get Samantha’s attention,” a source says, “including grinding her derriere on the glass partition that blocked off the booth.” But whatever Aubrey was selling, Samantha wasn’t buying. “Samantha totally ignored her,” said the insider.
