Justin Bieber raised eyebrows on Saturday by sharing a photograph of Kylie Jenner on social networking site Instagram.

The pop singer, 20, posed alongside Jenner, 16, and model Yovanna Ventura in Las Vegas ahead of the Floyd Mayweather - Marcos Maidana fight. The photo fueled reports of a feud between Jenner and Bieber's ex-girlfriend Selena Gomez, which upset fans.

In April Gomez, 21, abruptly unfollowed Jenner and her sister Kendall on Instagram just days after partying with the famous sisters at Coachella. Reports claimed the "Come & Get It" singer was left furious after Jenner was seen openly "flirting" with Bieber at a party he hosted and the photo he shared on Saturday did little to dispel feud rumors.

"Selena felt Kylie was flirting with Justin," a source told Us magazine with another adding "It got messy ... Selena said the Jenner girls were flirting with Justin and his crew. She was pissed and overreacted."

Fans of Gomez were left furious over Bieber's photo with Jenner, however, the pair is reportedly not romantically involved.

Both Bieber and Jenner, who share mutual friends, are believed to have stayed separately at the Hard Rock Hotel and Casino in Las Vegas. They both watched Mayweather defeat Maidana at the MGM Grand Garden Arena.

Jenner's sister Khloe was also present at MGM to watch the fight and she was accompanied by her rumored boyfriend French Montana, People magazine reported.

Despite reports of a feud between Jenner and Gomez, an insider insists that their issues have since been resolved. The former Disney star reunited with Bieber, who she has dated on and off since 2011, earlier this year however they reportedly split again after a fight at Coachella last month.

"Selena has no issues with the Jenner girls. They had an issue but they have cleared it up," a source said.

"She has always liked the Jenner girls. They had been fans of Selena since they were young," the source added.
