Just-in do it?

On Friday afternoon Justin Bieber indulged in a little bit of retail therapy at Niketown in Los Angeles, and the 21-year-old pop star was joined by at least two big bodyguards. He may look like a tough guy with tons of tattoos and saggy pants, but let's all keep in mind that he's 5'9" -- and that's likely on a good day, with shoes on.

But who cares about his height (or lack thereof)! The night before his shopping spree, the Biebs had dinner with on-again/off-again girlfriend Selena Gomez at Mastro’s Steakhouse in Beverly Hills. According to HollywoodLife, Justin picked Selena up from a hotel in West Hollywood, and though the restaurant was already closed, they went in and spent about 30 to 40 minutes together.

And then? The two got back into his car and went back to her hotel, but Biebs didn't get an invite to her room. Instead, the two spent about 25 minutes talking inside the car, she eventually got out and met up with a girlfriend and walked back to the hotel.

You KNOW Biebs wanted to show her his Calvins! Kudos to SG for playing hard to get, but we have a feeling he'll be making her say "Baby, baby, baby, oh!" by the end of the weekend. #jelenaforever

P.S. We love the fact that the Biebs ALWAYS has times to snap selfies with his fans:
