Ashlee Simpson and Pete Wentz "have everything they want", says pal

Ashlee Simpson and Pete Wentz are "cool" and have "everything they want", says the Fall Out Boy rocker's rapper pal Tyga.

Tyga -- who's signed to Wentz' Decaydance label -- insists the pair -- who wed Saturday -- do not need wishes of luck as they embark on their new marriage -- because they already have everything they want.

He says, "They're cool. They don't care about the media, they don't care about being famous, the money – they're young and having fun."

The rapper said he got to know the newly weds when singer Ashlee, 23, joined him and Fall Out Boy on the Young Wild Things tour a year ago. "She'd listen to my song and be like, 'this is my favorite song!' She's real cool."

He added, "They don't need no good luck. They don't need no wishes. They've got everything they want in the world."
