Selena Gomez is dating herself.

The actress-and-singer is glad her relationship with Jonas Brothers star Nick Jonas ended because being single means she can focus on what's most important to her.

Speaking about her relationship with the teen star, she said: "I'm happy that is all in the past now. I'm very much single, I'm dating myself now - I think if you don't love yourself first, no one else will love you."

Selena and Nick - who previously romanced Miley Cyrus - dated on and off between 2008 and April this year.

Although she has had hits with songs from her debut album 'Kiss and Tell' including 'Falling Down', Selena, 17, is looking forward to returning to the set of hit US TV show 'Wizards of Waverley Place'.

She explained: "I love music, but acting is where I started and what I enjoy the most."

The teen star is also set to appear in a new movie alongside Nicole Kidman, and admits she was terrified ahead of their first meeting.

She said: "You always get nervous when you meet an actor you really respect. But Nicole is amazing. She's so funny. I can't wait to start shooting."
