Justin Bieber Hugs 'Mystery Brunette' Who Isn't A Mystery, Pranks Internet, Readies For Floyd

Justin Bieber has set off romance speculation once more after hanging out with a pretty brunette at a Hollywood studio on Friday (September 13), who has been seen with the singer many times before.

Following his return from a brief trip to Canada where his father Jeremy underwent knee surgery, the 19-year-old was spotted filming an episode of "Funny or Die" with his buddies rapper Lil Twist, Lil Za, and Alfredo Flores in Los Angeles.

At one point during the fun, Justin was snapped greeting a female who looked very similar to the girl he sat front row with at Opening Ceremony's fashion show in New York last week.

The girl is rumored to be Jacque Pyles, who dated Bieber long before he met ex-girlfriend Selena Gomez.

Pyles was also the girl seen in an Instagram posted by the teen star on August 26, one day after MTV's Video Music Awards.

During a break the pair were spotted hugging in a familiar fashion. At the time, Justin was dressed in a smart but comic suit teamed with calf-length socks and red trainers, while the Pyles look-a-like wore distressed jeans and a black midriff top.

The superstar was later seen larking around shooting hoops on a basketball court with his friends.

Justin is currently on a break from his Believe world tour. He returns to the road on September 23 in Singapore before the last leg of his mammoth trek.

After turning heads during New York Fashion Week with a passing return to his throwback hair flip and a now-culled mustache, the prank-loving singer set the Internet alight on Friday.

Just hours after alluding to his Funny or Die date on Twitter, Bieber Instagrammed what appeared to be a photo of a copy of the script of the upcoming Batman Vs. Superman movie starring Henry Cavill and Ben Affleck, along with a caption that read, "#Robin??."

An absolutely delighted --- we jest ---Internet made its feelings known, while wiser heads directed the inconsolable to Bieber's "Funny" tweet.

But, nothing's been denied yet.

By way of an Instagram and a later tweet posted on Saturday, the pop prince more or less confirmed he will walk Floyd "Money May" Mayweather Jr. into the ring for his super welterweight face-off against Canelo Alvarez at Las Vegas' MGM Grand tonight.

"On my way to see the champ. #vegas," the teen singer tweeted.

Back in May last year, Bieber, Lil Wayne and 50 Cents walked Mayweather into the ring before the 36-year-old defeated Miguel Cotto battling for the junior middleweight title.

Tonight's highly anticipated fight is expected to draw an audience of millions around the world and a star-studded crowd which may see Diddy, Denzel Washington, Heidi Klum, Jack Nicholson, Kobe Bryant and more roll up.

And would you look at that? Ms. Jacque Pyles just happens to be in Vegas too.
