Justin Bieber, Jacque Rae Pyles: Wisely Keeping Schtum Over Romance Rumors

Justin Bieber and Jacque Rae Pyles have been spending a lot of time together.

The pair have known each other for at least three years and are thought to have previously dated. As a result, romance speculation is now in full swing.

The most recent sighting of the twosome saw the brunette and Bieber fly to Las Vegas aboard a private jet on Saturday ahead of Floyd Mayweather's boxing victory against Saul Canelo Alvarez.

Photographs of the 19-year-old boarding the jet with his three-year-old brother Jaxon, followed by Jacque sporting short shorts, a black top, and a pink shirt, did the press rounds shortly after.

Pre-fight, Bieber's tweets and Instagrams focused on the match to come, for which he acted as a hype man with the rapper Lil Wayne.

Meanwhile, Pyles, a singer, dancer, and School Gyrls alum, posted a snap of herself on the jet on Saturday wearing a matching, tight-fitting two-piece skirt and crop top by Motel Rocks.

It was captioned, "so obsessed with this outfit and my @teddierevival jewelry."

Speaking to E! News!, personal stylist Jazmin Whitley --- who helped Pyles prep for traveling with Justin to Vegas --- said:

"I did not fly out with her for this event."

"For this event, she [Pyles] came by my house," the stylist added."It was kind of last minute, she came over on Thursday and we got to hang out and try on a bunch of looks that I pulled for her. She was excited about attending the event. She is always out and about, and we are going to film a fashion segment soon."

Inevitably, echoing Ariana Grande's experience after she posted a kiss selfie with her former tour mate, Pyles has received online hate (as well as support) from over-invested Bieber fans since the Vegas trip.

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

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

Bieber's reps have wisely declined to comment on the teen singer's personal life and it seems Pyles is following suit.
