While speaking about her Stars Dance world tour and being single, Selena Gomez told E! News Thursday that she is having the "best year" of her life.

The 21-year-old attended the Flaunt magazine party at Hakkasan in Beverly Hills on Nov. 7 in a black cutout dress by Cushnie Et Ochs that had a modest length but plunging neckline. The singer added black pumps and burgundy lipstick to complete the look.

"It's good. I'm having fun," she said about how her year is going as it draws to an end. "This has been the best year for me: I just turned 21, my record, the tour. I have a really good thing going."

Asked if she has time to date, Gomez laughed and replied, "No!"

Her last relationship was with pop singer Justin Bieber. They began dating in 2011 and broke up in late 2012. The former couple were rumored to be on and off in early 2013 after photos surfaced of them together, specifically one of Bieber topless while Gomez hugs him.

Gomez kicked off her Stars Dance tour Aug. 14 in Vancouver and will continue to be on the road until Jan. 21, 2014, when she ends her concert series in Nagoya, Japan. She will return to her native hometown to perform during the Dallas Cowboys' halftime show on Thanksgiving Day. The team will play the Oakland Raiders at AT&T Stadium in Arlington, Texas.

"I'm from Dallas, so it's even scarier, but it's going to be great," Gomez said of getting on stage at the upcoming game. "I'm going to have all the food packed up from home and actually at the venue so I get to have a home cooked meal while I'm there."

Gomez has been sporting sexier outfits since her split from Bieber. She has walked the red carpet in a number of dresses with high-slits and revealing cutouts. Scroll through the images to see some revealing looks worn by the Come & Get It singer.
