KFed-Ex & Shar Part 2?

We all know Britney Spears's body and money pulled Kevin Federline away from his pregnant girlfriend (the couple already had 1 child) in 2004 - but could he be back in Shar's bed now that the Spears-Federline union is over?

KFed-Ex has been spending a lot of time with Shar Jackson and that's not abnormal considering they have two kids together (she has 2 with some other dude) - but "a source" told In Touch Weekly, "Shar was always there for Kevin. When things were really bad with Britney, she was a rock for him."

In February they denied the reunion but a KFed-Ex pal says it's only a matter of time before the couple reunite, adding, "Shar was his first love - plus, he's been saying how hot she looks."

She better look hot after spending $15k on a tummy tuck and breast lift! Now they have lots of money and Kevin actually brought some of it to the table this time...granted, it came from Brit but who cares!
