katecover.jpgKate Hudson kate2.jpg After seeing how hot his ex Kate Hudson's looking in her upcoming photoshoot for W, Lance Armstrong's gotta be kicking himself - and Kate's gotta be loving it!

As part of the profile accompanying Kate's sexy pix, a source tells W that the couple broke up after only three months due to Lance growing uncomfortable with Kate's ever-growing affection.

"Lance felt that Kate came on too strong, too fast," the source says. "She started talking about marriage and babies almost right away."

(Toldja!)

"Lance realized he wasn't so committed to the relationship and shouldn't pursue it any more. He freaked out at her clinginess and bailed."

Well, we're sure Lance will be singing a different tune once he sees how sensational Kate looks in W - seriously, who wouldn't want to get clingy with all that hotness?
