Justin Bieber just celebrated his 21st birthday earlier this month - and despite his young age, the "Believe" crooner is definitely a smooth ladies man!

As MstarsNews previously reported, the pop megastar allegedly "hooked-up" with "Love & Hip-Hop Hollywood" troublemaker Masika Kalysha after a wild night of partying - and the VH1 reality starlet immediately bragged about it on Instagram...

But apparently, JB also "romanced" another LA socialite during such b-day festivities!

YMCMB superstar Drake's rumored ex-girlfriend, Lira Galore.

According to the infamous gossip webloid bossip.com, the Biebs was spotted partying VIP-style at Miami's prime celebrity hot-spot IVY nightclub over the weekend. He was photographed "cuddled-up" in the corner with Miss Galore. The two spent the majority of the evening together - flirting and getting rather close. They even jammed-out to some Drizzy music!

DJ Khaled hosted the Friday night event (March 6), with surprise special guest DJ Mustard. In fact, fans can expect an awesome collaboration featuring Bieber and Khaled sometime soon. Check out a slew of viral snapshots here.

The "YOLO" hypeman and brunette bombshell were never officially dating, but they were briefly involved in some sort of sexy fling back in October 2014. Galore even joined Drake on a hot-and-steamy island vacation, although both insisted the trip was "just business." Right... surly Galore tempted the Toronto emcee with her stunning bikini body!

The Instagram vixen is known for her rather eye-popping physique:

Wonder if the new pals were still hanging-out when Galore rocked this skimpy swimwear?

lira_galore: "Late nite Lira."

But Drizzy shouldn't be mad - apparently, he's now dating aspiring model, Bernice Burgos.

Meanwhile, Bieber continues enjoying the "single life" as a free, now legal man. Oh, and this...

justinbieber: "Hard work. Dedication."

Right now the Biebs is just having fun, and probably not ready to settle-down again anytime soon...
