GIGGLING Britney Spears has made her ex Justin Timberlake look small — by hinting he has a tiny willy.
Pop hunk Justin is dubbed “Trousersnake” because he is such a big hit with the ladies.
But Britney, 21 — who lost her virginity to the singer — suggested on US telly he was actually a huge disappointment in the pants department.
Talking about her break-up with Justin, 22, she said she felt “just a little bitter”.
She laughingly stressed the words “just” and “little” — while using her thumb and finger to indicate a teeny length.
An insider on the MTV special, In The Zone & Out All Night, said: “She didn’t actually use Justin’s name but as she always says he has been her only lover it must have been him she was talking about.
“After she said it she fell about laughing with her camera crew. Forget Trousersnake, it’s more like Trouserworm.”
The show will be screened on MTV in Britain on December 2, Britney’s birthday.
It was in stark contrast to another appearance on US TV last week, when Britney burst out crying talking about Justin, who now dates Cameron Diaz.
