Selena Gomez's Promising Night at Nobu

Looking more and more mature by the day, a stylishly dressed Selena Gomez attended the launch party for 'Promise' at Nobu London in London, England on Wednesday evening (September 29).

The "Wizards of Waverly Place" cutie worked the arrivals area while greeting Fawaz Gruosi at the event honoring Cheryl Cole and de Grisogono's new capsule ring collection.

The UK outing comes as Miss Gomez has been traveling Europe to promote her recently released album, A Year Without Rain.

Also doing quite well in the clothing industry with her K-Mart Dream Out Loud line, Selena recently told WWD, “It’s crazy and so great. All of my hard work has truly paid off, and I feel so happy. I’ve always wanted to do a line. It was about finding the right company to partner up with, and I think Kmart truly got what I wanted to do with my fans.”

She added, “I didn’t just want to slap my name on it. I wanted it to be real clothes that real people could wear. My mom wears some of my shirts. I wanted to make a really good-quality clothing line, and I think Kmart really understood that.”
