Washington, Dec 15 : Popstar Pete Wentz is keen to patch up with The Killers rocker Brandon Flowers, as fatherhood has mellowed him down.

Pete, who is married to Ashlee Simpson, recently became a father to son Bronx Mowgli and wants to end his tiff with Brandon.

"My biggest public regret is the fall-out with The Killers. Fatherhood has made me see our feud is petty bulls**t," Contactmusic quoted Pete, as saying.

Pete and Brandon fell out in 2005 when Brandon claimed he wanted to "destroy emo", as he thought the gloomy lyrics were a bad influence on kids.

Meanwhile, Pete was also in news for denying claims that he is struggling to sell his son's pics to magazines. (ANI)
