OK! Exclusive: Fergie Does Not Want To Lose Her Fit Body But Josh Duhamel Wants Baby No. 2!

Fergie may be obsessed with her adorable son Axl, but she is not necessarily ready for him to have a sibling, much to husband Josh Duhamel’s disappointment!

A source tells OKMagazine.com that her gym dedication is veering on an “obsession,” and making Fergie hesitant to have baby No. 2.

The 40-year-old clearly worked super hard on her fitness to get her pre-baby body back after giving birth to her first child in 2013.

She has happily been flaunting her bod recently, both at Coachella and during a beach vaca with hubby Josh earlier this month.

So “another baby just doesn’t fit in with Fergie’s life at the moment,” a pal says, though Josh is “desperate to have another kid.”
