It seems Justin Bieber is very excited about the upcoming release of his new single Cold Water. The 22-year-old singer on Wednesday (13 July) posted a GIF video of himself and a friend on Twitter, where they were seen doing a synchronised backflip on a trampoline.

The Sorry hitmaker has teamed up with Major Lazer, Ed Sheeran and Benny Blanco for the song, which releases next Friday (22 July).

The collaboration is expected to be another hit, given that Beiber's previous collaborations with Diplo and Skrillex in Where Are Ü Now and with Sheeran in Love Yourself were massive successes.

Meanwhile, there is another reason for Bieber to be happy, as his Purpose Tour merchandise is going on sale at Barneys stores across the US from 16 July. The famous retailer for the first time will be selling a musician's tour merchandise, ranging from T-shirts, jerseys, jeans, all the way to $1,675 (£1266) leather jackets.

"It was a no-brainer for me," Jay Bell, a senior vice president at Barneys who oversees the men's designer section, told the New York Times. "It is the first time we've done it, but it felt right. It felt like something that would resonate with our customers, and that could sit seamlessly with the other brands we sell."
