Justin Bieber and Selena Gomez Reunite in L.A… and N.Y.C.?

Justin Bieber and Selena Gomez are having a hard time walking away from each other.

Technically off-again after their split in early January, the exes spent a lot of time together over the weekend. In addition to an apparent sleepover on Friday night – Gomez was photographed exiting Bieber’s Los Angeles home – they met up Saturday night as well ... and a New York City rendezvous could be next!

Gomez hit Soho House in West Hollywood on Saturday night to see her pals from the girl group YLA in their private concert. E! News reports that not long after she arrived, Bieber appeared and took a seat next to Gomez.

Needless to say their appearance together didn’t go unnoticed – even by the band. YLA’s Brooke Adams tweeted about the sighting, writing, "No big deal.. Bieber and Gomez front seat at our first show. Musta been the music."

E! noted that while Bieber, 18, and Gomez, 20, were side-by-side for the show, they did not – we repeat did not – engage in any PDA, but there could be more chances for that in the near future!

While the Biebs is already in NYC getting ready for “Saturday Night Live” hosting duties this weekend, Gomez is also headed to the Big Apple for New York Fashion Week. She plans to attend the Adidas NEO fashion show on Wednesday. She’s the brand’s guest designer through a three-year partnership and helped select the 30 looks that will be seen in the runway show.

Coincidentally, Bieber also works with Adidas – he’s the global style ambassador for the brand – though he isn’t expected at the fashion show. However, that doesn’t mean they can’t meet up before or after – or announce to the whole world that they’re back together during a fun skit on “SNL.”

We’ll be on the lookout… as will all the Jelena diehards.
