Justin Bieber and the One Direction lads are good friends, having hung out when the band were in the US earlier this year.
But could Harry Styles be about to outshine the Canadian singer in the popularity stakes? It appears so.
According to Star magazine, Harry has been told he could be just as big as Bieber, if he plays his cards right.
A source said: “Harry was told he can be as huge a global star as Justin.
“He laughed about it, but he has started to realise there is real truth in that.”
Don’t panic 1D lovers. Despite recently taking a solo trip to America for a ‘big money deal’, Harry’s heart lies with firmly with One Direction.
The insider insisted: “He loves being on One Direction so it’s unlikely he will leave permanently, but he definitely wants to do some stuff on his own too.”
And it doesn’t look like Justin is too worried about Mr. Styles stealing his pop prince crown.
He has a lot of love for One Direction and thinks the world has been waiting for a fresh young boyband like the X Factor stars.
He told The Mirror: "They look great, they sound great and, when you add their British accents into the mix, the American girls are going crazy for them.
"Sure you need the talent, but you need to win over the American public, that’s what it is all about. One Direction are genuine good guys.
"The industry needs a fresh boy band, and by the end of this year they will be the biggest boy band in the world.”
