The 21-year-old star was announced as the new face of Calvin Klein underwear in January and has now revealed he gets sent so many pairs of the briefs by the brand, he refuses to wear them multiple times.

During a segment on 'The Late Late Show', host James Corden asked the rapper: "Do they send you unlimited Calvin Kleins? Do you just wear them once and throw them away?"

Justin then confessed: "They send me a lot, boxes and boxes of Calvin Kleins... Yeah, I definitely don't wear them twice. There's so many."

The 'Boyfriend' hitmaker will be hoping his box fresh undies will be enough to seduce 19-year-old make-up artist Jayde Pierce, who is reportedly the singer's latest love interest.

Although the pair have not commented on rumours of their relationship, they have been pictured hanging out together on numerous occasions in the past few weeks, enjoying a dinner date, a hike at Runyon Canyon in Los Angeles and trips to the gym together.

However, Justin - who split with long-term girlfriend Selena Gomez last year after four years of dating - has recently been romantically linked to model Kendall Jenner, as well as Australian model Shanina Shaik who one source close to the singer described as his "dream girl".

The source said: "Justin liked Kendall, but he is really into Shanina Shaik. Justin's definitely hooked, Shanina is his dream girl."
