And it seems 'The O.C.' actress has no issues with her ex dating Hilton, for Barton, who earlier dated oil scion Brandon Davis, a close pal of 'The Simple Life' star, is tired of 'immature' guys in her life.
"I'd like someone who's mature. God, I can't take another immature person," the Sun quoted Barton, as saying.
Earlier, the actress was shocked to see Adler's bare-all pics on the site, which put out a few video clips obtained from the hotel heiress' belongings from a storage locker.
However, Adler had said that Barton wasn't amused by the news, and that it was more difficult for her than for him in many ways.
"Mischa wasn't too excited, to say the least I think it was actually worse for her than for me in some ways," the Sun quoted Adler, as saying.
29 year-old Cisco, who is the lead singer of rock band 'Whitestarr', had added that he would be more cautious about his sexcapades.
"So, yeah, I'm gonna try to keep my pants on from now on," he said.
