Justin Bieber jetted into Las Vegas with family, friends and former flame Jacque Rae Pyles, ahead of his "hype man" walkout with rapper Lil Wayne for Floyd Mayweather's super welterweight face-off against Saul "Canelo" Alvarez at the MGM Grand last night.

But while the thousands strong crowd that included Owen Wilson, Jack Nicholson, William H. Macy, Bar Rafaeli, Denzel Washington, Pete Berg, Liam Hemsworth, Magic Johnson, LL Cool J, Michael Phelps, Wayne Gretzky and Don Cheadle, and the millions tuning in ensured the fight was a high glamour event --- Bieber made sure he kept his pals and family close.

On Saturday, Bieber was spotted boarding a private plane with dancer, singer, and School Gyrls alum Pyles, whom he is rumored to have previously dated.

It's not known if the twosome are currently in an intimate relationship, but Pyles was one of a group of friends who accompanied Justin on a vacation to the Bahamas in August.

In addition, the pretty brunette featured in an Instagram the teen singer posted the day after the 2013 MTV Video Music Awards in Brooklyn, New York.

Pyles sat front row with Bieber at Opening Ceremony's show during New York Fashion Week, later clubbing with the singer and his buddies at the 1 Oak nightclub on September 8.

Jacque also was seen hugging the superstar outside the "Funny or Die" studios in Los Angeles on Friday.

The three-year-old was seen boarding his famous brother's private Vegas-bound flight on Saturday.

Once at the MGM venue, the "Beauty and A Beat" star was seen affectionately nuzzling the blond toddler as the step-siblings headed to the VIP area.

Earlier in the day Bieber kept his legion of fans updated before jetting out of Los Angeles, posting a message to his over 44 millionsTwitter followers, writing,

"On my way to see the champ. #vegas (sic)."

Over on his Instagram account, the pop star posted a pre-fight picture of himself and Floyd before he walked the boxing hero out to his May 2012 victory over Miguel Cotto alongside Lil Wayne and rapper 50 Cent.
