It's good to know that Pete Wentz won't be jostling for space with baby Bronx Mowgli at wife Ashlee Simpson's breast.

After dishing about the couple's healthy sex life, the Fall Out Boy rocker has been equally candid about sampling his missus' breast milk.

His verdict? It tastes "soury” and “weird” apparently.

But luckily son Bronx is more of a fan: "The baby loves it, it’s the only thing he’s had a chance to have."

Pete also revealed on SIRIUS' The Morning Mash Up! on Monday that he put on some sympathy pregnancy weight.

He said, "I gained 10 pounds at least. I usually hang out around 135, 134, I go up to about 140, and when I hit 148, I get fat face.

"I’m working out a little bit, trying...I mean last night I decided to eat Virgil’s [BBQ] at midnight which is never a good idea...I’m feeling that a little bit today.

"For the most part, we’re going on walks – that kind of stuff. I think it comes off easier for her because she gets to breast feed and I don’t have the luxury of doing that."

Possibly time to stop talking now, eh Pete?
