Justin Bieber And Ashley Moore Date Last Thing On Selena Gomez's Mind

Justin Bieber's lunch date with model Ashley Moore has sent his fans and media into a speculative frenzy. But, today of all days, the one person who's got other things on her mind is Selena Gomez.

Tonight, the "Come and Get It" singer will take to the stage in Vancouver, British Columbia to kick off her 52-date Stars Dance world tour, and the 21-year-old has been a bag of nerves.

"I definitely have anxiety. I'm very nervous, but in the best possible way," Gomez told MTV News at her last dress rehearsal at the Citizens Bank Arena in Ontario, CA., earlier this week.

"I love being nervous.The adrenaline takes over and it just makes me want to give my all so I'm really nervous," she admitted.

Adding that she has "a lot to prove" and "live up to," the starlet said she has been putting in eight hour a day rehearsals to create the kind of show she hopes will inspire audiences the same way Britney Spears' extravaganzas inspired her.

Even though it's likely the Latina has heard about Justin and Ashley's lunch date, for now at least, it seems she is focused on pulling out the stops for her big opening night.

Despite all the rumors that Justin and Selena re-ignited their relationship earlier this year and his appearance at her Malibu birthday bash with a red rose, the ex-Disney star has since said she is happy being single.

Having said that some reports say the pair have an understanding and "hook up" occasionally, so who knows?

Over in Justin's corner, most outlets are reporting he is dating Ashley and off the market.

The "Beauty and Beat" singer was photographed Tuesday picking up the 20-year-old model in his new Ferrari before whisking her to Bouchon, a très fashionable French restaurant in Beverly Hills where they apparently caused quite the stir when spotted.

The pair first appeared on the social radar together on New Year's Day, with Ashley later pictured at a Fourth of July party attended by Bieber and mutual friend Lil Twist who introduced them, Daily Mail Online reports.

It's always a guessing game attempting to read body language, but from X17.com's pictures of the twosome they looked very comfortable and at ease with each other.

While some observers have suggested Ashley is only with Justin for his name and money and that he is trying to make Selena jealous, Metro posed pros and cons on their possibly genuine coupledom.

In an unrelated interview, Ashley, who is signed to Nous Modelling Agency in L.A. came across as an uncomplicated girl kept ''pretty busy'' by her career who enjoys the gym, surfing, spending time at the beach, and writing.

At 5'8, the curly-locked beauty won't tower over Justin and her sporty lifestyle may calm his fast-paced, controversy plagued one.

In addition, for all the reasons below and more, she may just take the young Canadian's mind off those recently surfaced nude photos.
