Selena Gomez grabbed lunch with her mom at The Little Cafe in Encino on Wednesday afternoon, and after that the singer/actress headed to a meeting in Century City. When asked if she's dating 17-year-old pop star Austin Mahone, the 21-year-old singer politely ignored reporters and photographers and slipped into her black BMW SUV.

There was a rumor going around that Taylor Swift reportedly set the two up, and though a source told Us Weekly that Gomez and Mahone "[are] seeing each other," another insider told People that "maybe they are more than just friends but they are certainly not dating." Ok, so they may not officially be a couple, but no one's denied that the two are hooking up!

Austin himself posted this pic to Twitter in October ...

"They've been hanging out over the last few months," the source added. "They have a lot of respect for each other." Mahone chatted about Gomez at the Universal Music Group 2014 Post Grammy Party on Sunday and told the mag, "We're super close friends. She has some new music coming out. She showed me some of her music and it's incredible."

Seeing as Justin Bieber has moved on with Miami model Chantel Jeffries, maybe Selena is looking for a rebound as well? Austin seems like a nice little dude, but keep in mind, he's just SEVENTEEN! We know Selena likes 'em young (Bieber was 17 and she was 19 when they started dating), and it seems like she is taking a page straight from the book Taylor, who famously romanced Conor Kennedy when he was an 18-year-old high school student and she was 22...

P.S. The outfit Selena wore today? SO much better than yesterday's!
