Bieber's fans really have no age limit. Because even 36-year old Caroline Flack has gone wild when got the chance to hold Justine Beiber's worn underwear. Isn't that a dream come true?

The TV presenter admitted during a magazine interview that she sneaked into Beiber's dressing room of X Factor and stumbled upon the star's Calvin Klein's underwear.

"We found his pants once in his dressing room at X Factor !" she confessed.

"He was in Simon Cowell's dressing room, the one with the bath in it, and me and Olly were doing X Factor, so we shared a dressing room down the other end. We all went in there afterwards, and Justin had left his pants!"

Justin, who is 22, has been ordinarily known for showing off his underwear, much more when promoting a brand. The young superstar just recently modelled for Calvin Klein, that resulted in fans go crazier.

Flank, who is 14 years older than the singer, still finds him satisfying and feels lucky for such a blessing in disguise.

But, it seems like it was just a short dream come true, when Flank lost possession of the underwear, as co-presenter Olly Murs took them when she's away.

"I think Olly's still got them actually. They were Calvin Kleins - I didn't look, some of us did but I didn't..." Flank added.

The Love Island host admitted in Glamour magazine interview that she's now dating again, but still feels not yet ready for a new relationship.

"I haven't been in love for so long that I've forgotten what it feels like to want to tell everyone 'look how happy I am!'"

Amid Beiber fantasies, TV host has been seeing with a new beau, Blue Logan.

Flack's comment was made after footage went viral showing Bieber involved in a street outrage in Cheshire's Frodsham, where the singer's convoy was driving on a wrong side of the road.
