Jessica Simpson has a back-up plan if she fails to settle down and have a baby by the age of 40 - she'll have kids with her gay best friend and hairdresser Ken Paves.
 
Simpson admits her maternal instincts have gone into overdrive since becoming an aunt to nephew Bronx Mowgli - her sister Ashlee Simpson's now 16-month-old son with rocker Pete Wentz.
 
The singer/actress has yet to find lasting love following her 2006 split from ex-husband Nick Lachey - but the blonde beauty, who turns 30 in July, is refusing to let her single status halt her plans for children.

Simpson reveals she is willing to start a family with Paves if all else fails - and the openly gay stylist has agreed to father her babies.
 
She says, "I can't wait to have kids... Honestly, if I don't have kids by the time I'm 40; my best friend Ken Paves and I are going to have children. Why not?"

However, Paves admits he isn't as patient as his best pal - because he wants to be a dad before he hits the milestone. He adds, "I'm ready now! I've been trying to convince her to do it before I turn 40, which is two years."
