Justin Bieber cheers on boxer Floyd Mayweather after jetting in to watch title fight with former flame Jacque Rae Pyles

They used to date back in 2009, before Selena Gomez came along.
And Justin Bieber appears to be rekindling the flame with Jacque Rae Pyles as he was spotted jetting in to Las Vegas with the singer and actress on Saturday.
The trip was to support his personal friend and super welterweight champion boxer Floyd Mayweather as a hype man in a title fight with contender Saúl 'Canelo' Álvarez.

The hype: Justin Bieber and Lil Wayne walked out the champ Floyd Mayweather to his fight at the MGM Grand in Las Vegas, on Saturday night

The 19-year-old may be retaining some feelings of affection for the School Gyrls member as he brought her along for the puddle jumper flight.
And it was just in late August that the two were believed to be enjoying a romantic holiday together in the Bahamas.

The two music stars got into the ring with the boxer, working up the crowd as a kind of specialized version of super star hype men - with Wayne, 30, spitting out bluster via high velocity rhymes.

Mayweather won the fight with a majority-decision victory over Canelo after a typical performance for the champ.

The star athlete danced around his much younger opponent for most of the later rounds, slipping punches, and bicycling his legs and scoring points rather than trying for a knockout.
Meanwhile, leading up the fight the Beauty And A Beat singer remained mum on Twitter about Pyles accompanying him on the adventure.
Instead, Bieber stayed focused on supporting his sporting idol Mayweather.
