The 22-year-old singer jetted off to Cabo San Lucas, Mexico, with the model for her 18th birthday and has seemingly amped up the heat after the sizzling pictures of the new couple locked in a series of steamy embraces - and with Justin semi-naked - have emerged on the internet.

The star's huge fanbase, who are also known as 'Beliebers,' quickly reacted to the shots and wondered was he making a "sex tape," with the hashtag #justinssextapeleakedparty trending online on Sunday (28.08.16).

In one of the pictures, Sofia is wearing white shorts and a black bikini top with her legs wrapped around the hunk as he holds her up and plants a kiss on her lips, and another shows Justin bending over her and her legs in the air.

Referring to the fact the 'Cold Water' hitmaker recently deleted his Instagram account, one fan wrote: "If you want privacy stop doing everything in public #justinssextapeleakedparty"

Another said: "Thanks Justin. I officially don't know how to defend you in front of my friends/family anymore. #justinssextapeleakedparty."

Whilst another user agreed, adding: "LOL at Justin Bieber. Talking about privacy when you literally have sex in public. Cmon fam, you know they always catch you."

The pair are reportedly staying at Las Ventanas al Paraíso, a luxury Rosewood resort and confirmed their romance two weeks.

However, the union was met with drama, when the pop sensation's ex-girlfriend Selena Gomez became embroiled in a public spat with the star and scolded Justin when he threatened to make his Instagram page private, because fans lashed out over pictures of his new love.

True to his word, Justin disappeared from the photo sharing site and Selena is now said to be stressed and needing time off work to rest.

Meanwhile, it's not the first time the star has had his private parts splashed over the internet.

Last year photographs of the star walking around on holiday naked sent the internet into a frenzy.
