Your missus is not going to be happy about this, Pete Wentz, and neither will your son in about a few years’ time.

In what must be about one of the tackiest interviews of the year, Fall Out Boy bassist Pete Wentz was a guest on Howard Stern’s radio show to promote his band’s new album, “Folie A Deux,” and instead made a complete fool of himself giving way too much information about his sex life with Ashlee Simpson.

Wentz, 29, and Simpson, 24, welcomed baby boy Bronx Mowgli Wentz on Nov. 20, just months after marrying. Since the birth of his first child, Wentz has been kind enough to share that the baby was a “happy accident” that has prompted him to mature more quickly.

In case you want to learn more about the life of the Wentzs, in particular their sex life, generally and post-baby, the bassist is more than happy to share. He found the perfect medium too, on shock jock Howard Stern’s show.

He revealed that “Texan girls are fun” and that he and Ashlee have an “amazing” sex life. And while his wife is still recovering after giving birth, they find “other fun stuff” to do.

Whoa there, Petey, we didn’t need to learn all these details (he said a lot more actually but we will not be repeating it here). Wonder if Joe Simpson, father and manager to Ashlee and sister Jessica Simpson, will have something to say about this? And if he does, how twisted will it be?

Before starting to make his confessions to Stern, Wentz said Ashlee had asked him not to say anything “crummy” about her during the interview. Nothing crummy at all. He just did his best to portray her as “the ultimate” and detailed their first time in bed, characterizing it as “the single best sexual encounter” he ever had.
