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.
