Bieber Las Vegas! Justin Parties After Tour Return And Week Wrap

Justin Bieber let his pompadour down in Las Vegas on Friday, having completed almost a week of shows on his recently resumed Believe world tour.

The 19-year-old first performed at San Diego's Valley View Casino Center last Saturday, June 22, before two star-flecked shows at Los Angeles' Staples Center June 24-25, then San Jose June 26, and Las Vegas' MGM Grand Garden Arena on June 28 to 16,800 euphoric fans.

It was a somewhat different reaction to Bieber's last appearance in the bright lights, big money, big action city, when he booed by a furious crowd as he accepted the Chevrolet Milestone gong at the Billboard Music Awards.

In fact, at each of Bieber's five shows fans have held up signs reading "Unbreakable," "Love," "We Will Always Be Here," "Still Heart Kidrauhl" and "This is Forever," in powerful demonstrations of the heartthrob's relationship with his 'Beliebers.'

Rap star Wiz Khalifa was one of those in the audience on Friday. The "Work Hard, Play Hard" artist later tweeted his seal of approval, writing:

"Justin Bieber is a pure star. I'm honored."

The Canadian teen's own verdict?

"Great show Vegas."

Post-show, Bieber and his crew were apparently ready to cut a rug, decamping to the Las Vegas mansion of music producer Jamal Rashid, also known as Mally Mall.

If that name sounds oddly familiar, it's because it is. Rashid is the producer who gifted "Mally the monkey" to Bieber for his infamous 19th birthday.

Justin, reportedly, enjoyed a long night of fun with his friends and partied into the wee hours of Saturday morning.

"Bieber went back to his hotel at 6 am with a huge entourage," a photographer waiting at the hotel confirmed.

From the pictures, there was no sign of Jordan Ozuna, the Las Vegas ex-Hooter waitress seen in recently surfaced video footage, which appeared to show Bieber and the blond getting intimate at the city's Indoor Skydiving facility.

It's possible the star had a lot on his mind as he partied last night. As well as the Ozuna speculation, this week saw revelations of the singer's ban from the facility for alleged non-payment for services.

Bieber was also hit by a virulent TMZ story in which it was claimed that an alleged rider from one of the singer's photoshoots contained a series of despotic demands, including instructions "not to talk to the talent," "no cell phones" and "No Selena [Gomez] music on set."

The story has since been denied by Bieber's rep who dismissed the document as a complete "fake."

However, the singer has also been slapped with an assault and battery suit by a paparazzo. Jose Ozmin Hernandez Duran alleges Bieber martial kicked him in the abdomen then punched him in an alleged incident last May, after he took photos of the star and his then girlfriend Selena Gomez at a shopping center in Calabasas, Calif.

Although the Los Angeles County District Attorney's Office declined to bring charges against the pop star, due to insufficient evidence and Duran's "superficial" injuries, the paparazzo is now suing Bieber for unspecified monetary damages for his alleged "severe and extreme emotional distress."

Bieber is also facing lawsuits from two separate paparazzo's in incidents alleged to have occurred outside Miami's Hit Factory Recording Studio on June 5.

On a lighter note, a brand new waxwork of Bieber was unveiled at Madame Tussauds Washington D.C., and the singer set an Instagram record by becoming the first user to hit 1 million 'Likes' on his first video after using the application's new feature.

The pop prince also passed 41 million followers on Twitter, which may have softened the blow of losing his VEVO crown for "Most Viewed Video in 24 hours" to Miley Cyrus' "We Can't Stop."

The seemingly inexhaustible singer is also rumored to have enjoyed a late-night movie with Gomez at the ArcLight Theater in Sherman Oaks, CA, on Thursday, June 27. There are conflicting reports on whether the Spring Breakers actress was actually there.

In a new interview with Us Weekly's Collector's Edition, Bieber shared his reasons on why the end of a relationship doesn't have to be the end of everything, which may explain the movie night.

"As long as people are kind to each other during a breakup, there is no reason [why] they can't be friends," Justin told Us Weekly, adding that, "a lot of people give me relationship advice."

Bieber also told the magazine he wants to "get married and start a family" while he's young.

Explaining that he sees his maternal grandparents "Bruce and Diane Dale" as his relationship role models, the singer said: "They love each other so much, after so many years! When I'm their age, I want to be as in love with my wife as my grandfather is with his."

Contexted by a ever-growing list of police investigations, lawsuits and constant media focus, Bieber revealed the best piece of advice he's been given to date.

"Be patient and listen." But the teen star did admit, "I'm still growing. I'm trying to be a better person every day."

The "Baby" singer rounded off his stay in Las Vegas by attending the Saturday world premiere of Cirque du Soleil's new "Michael Jackson One" production at Mandalay Bay Resort and Casino.

A huge fan of Jackson, Bieber went to the show with R&B producer Rodney Jerkins --- who worked with Jackson --- tour buddies, and manager Scooter Braun.

Notably, the production features a hologram of the late world famous entertainer.

Other stars at the event included matriarch Katherine Jackson, Prince Jackson and other members of the Jackson family, Neil Patrick Harris and his partner David Burtka, BAD 25 director Spike Lee, fashion designer Roberto Cavalli, David Arquette and Allison Janney.

Justin declared his appreciation for Jackson on Twitter after the show, before letting Denver know the Believe extravaganza was heading their way.

Bieber is next set to perform at Denver's Pepsi Arena, Colorado, on June 30.
