Selena Gomez and Austin Swift may be involved in a romance.

Selena Gomez & Justin Bieber Flirt War Continues On Instagram

According to a new report, the 23-year-old singer and the brother of her best friend, Taylor Swift, were quite close during Sunday night's Vanity Fair party after the Oscars.

“There wasn’t one time that I didn’t see them (Selena and Austin) together," an eyewitness told Hollywood Life on Monday. "Granted, Taylor was also with them, but at one point it was just the two of them dancing while Taylor was dancing with Lorde and Brie Larson. Selena and Austin weren’t holding hands or anything like that, but they do make a good looking couple, and they looked like they were having a great time together."

The report also claimed Selena and Austin were spotted getting cozy at the Feb. 15 Grammy Awards. During Taylors's performance of “Out Of The Woods,” Selena and Austin appeared to be enjoying one another as they rocked back and forth to Swift's hit track.

Selena has been tied to a few different men in the last few months, including her ex-boyfriend, Justin Bieber, and One Direction singer Niall Horan. However, it was Samuel Krost with whom she appeared to be the most serious. After dating in November, the pair appeared to take some time off, but in January, they were seen out to dinner twice before Selena confirmed she was single shortly after Valentine's Day.
