Selena Gomez's ex-boyfriend, who just turned 21, "couldn't stop flirting" with 29-year-old Irina while he partied together with Kendall Jenner and Hailey Baldwin, reported Ace Showbiz.
"Bieber was surrounded by all the Victoria's Secret models. It was like a line of angels outside his cabana," an insider said.
The 21-year-old singer flirted with most of the "newbies," but only had his eye on Irina for most of the night and the model also reciprocated by flirting back, said the insider.
