Helloooooo Selena!

We aren't sure if Selena Gomez is trying get some attention from rumored new man Austin Mahone who was recently spotted hanging with Kylie Jenner in NYC -- or if she's trying make Justin Bieber jealous after his recent Panamanian vacation with the soon-to-be-forgotten Chantel Jeffries -- but either way, she's certainly grabbed our attention. The 21-year-old starlet had all eyes on her when she wore an oversized shirt without a bra for a lunch in Encino, Calif., on Friday afternoon.

There's no doubt in our minds that the often-photographed Selena knew that she was sneaking us a peek at the goods when she opted for a semi-sheer, white button-down, which was unbuttoned rather low, and no bra.

For the luncheon, the former Wizards of Waverly Place star paired the button-down with ripped jeans, a gold cuff, gold earrings and wedge T-strap sandals. If she was going for effortlessly sexy -- she definitely nailed that look.

Recently Selena has been romantically linked to 17-year-old popstar Austin Mahone, who is often dubbed, "the next Justin Bieber." However on Wednesday, Austin denied the rumors to people People magazine, saying, "We're just friends."

The teen went on, "She's really cool...I mean, I think she's really pretty but every time I'm in L.A., she's like, 'Hey you're in L.A., lets hang out.' So it's cool."

We have no idea what "So it's cool" actually means -- but it sounds like something is brewing with Austin and Selena.

If the brunette beauty was trying to raise some eyebrows -- she did a good job!
