Max George thinks Nina Agdal "deserves" the Sports Illustrated Swimsuit cover.

The Wanted singer announced he was dating the model in October last year, but they've been hit by rumours of a split this month.

He's now taken to Twitter to wish the 21-year-old beauty luck with her modelling assignments, proving they are still on speaking terms.

"Fingers crossed for @NinaAgdal to get the new @SI_Swimsuit cover. You deserve it sweet! X (sic)" he posted to his followers.

Models who have appeared on the cover of the magazine's annual swimsuit issue include Kate Upton, Irina Shayk and Brooklyn Decker. This year's cover star will be announced on Jimmy Kimmel's talk show tonight.

As of yet, Nina hasn't written back to the 25-year-old star.

According to British newspaper The Sun, Max called time on his relationship with the fashion star as they wanted "different things" and had "grown apart".

While neither has confirmed the breakup, Nina was spotted out with actor Leonardo DiCaprio earlier this month, who has dated stunning models such as Erin Heatherton and Bar Refaeli in the past.

It's been a tough time for Max, who faced a backlash from the rest of The Wanted when he spoke out about their split.

Max, Siva Kaneswaran, Tom Parker, Jay McGuiness and Nathan Sykes will go their separate ways after finishing their Word of Mouth World Tour in May.

Max offered up details about the decision during an interview with a UK newspaper, which prompted angry tweets from his bandmates.

It seems there's no bad blood though as the boys headed off on tour today, with their first show in Dubai scheduled for tomorrow.

"Dubai here I come! Never been, brought my finest swim shorts, which I've had for over a decade :) (sic)," Max excitedly posted.
