Justin Bieber is not afraid of displaying his transformation from a boy to a man as he partied at a Texas strip club this Friday (Oct 18th).

The gentleman's bar was called 'VLive' and the 19 year-old singer was spotted walking around with no shirt on with his pants half way down his legs, reports TMZ.

The website claims Bieber got friendly with a local stripper by touching her behind at the notoriously raunchy strip joint.

The ass grab didn't go unnoticed as before long it was doing the rounds on social media networks with the stripper involved, tweeting, "He touched my ass I almost fainted."

She also posted "I've danced for a lot of celebrities and they normally don't phase me but Justin had me in shock!"

The 'Love Me' singer may have hit the late-night strip club to support his upcoming movie 'Believe 3D' which is meant to follow Bieber's journey from a teen into a young adult. There are better ways to demonstrate this than slapping a strippers rear-end.

The stripper, who will no doubt be hated by all of the Canadian singer's loyal fans, hinted that boxing champion Floyd Mayweather was also in attendance at the club and was very generous as she posted a tweet saying, "S/O (Shout out) to @FloydMayweather Too!! MoneyTeam went In!!"

The post came after she admitted, "I am now a @justinbieber Fan."

What must Justin's poor mother, Pattie Mallette, be thinking?

She recently discussed letting her superstar son become more independent in a teaser clip for the upcoming movie, "I think it's hard for parents to let go, but it's really exciting too to see him maturing," Mallete said.

'Believe 3D' is due to hit theatres on December 25th 2013.
