Justin Bieber Dating Jacque Rae Pyles? 'Heartbreaker' Flies Ex-Girlfriend to Las Vegas on Private Jet for Floyd Mayweather Jr. Fight, Selena Gomez Relationship Over?

Justin Bieber flew out to Las Vegas on his private jet to witness Floyd Mayweather Jr. fight against Saul “Canelo” Alvarez on Saturday, September 14. The "Heartbreaker" crooner had a small group of friends tag along... including ex-girlfriend Jacque Rae Pyles. Are the two "secretly" dating again... and does that mean Selena Gomez is officially out of the picture?

According to HollywoodLife.com, 19-year-old Pyles was spotted stepping off of the Biebs' private jet in a cute pair of denim short-shorts. The young beauty and Bieber were not photographed together, but rumors suggest that a rekindled romance isn't totally out of the question. Later in the evening, Pyles posted this sexy snapshot on Instagram:

Back in August, Bieber and Pyles were spotted together on a romantic dinner "date" in Los Angeles. Then on September 10, they sat side-by-side during New York Fashion Week's Opening Ceremony. The duo briefly dating in 2009.

So, is Selena Gomez totally out of the picture now?
