Demi Lovato is bettering herself

Demi Lovato is trying to "better" herself in the wake of her split from Wilmer Valderrama.

The ‘Confident’ singer – who checked into rehab in 2010 at the age of 19 to be treated for alcohol and drug abuse, as well as an eating disorder and persistent self-harming – recently announced she and the actor had separated after almost six years together and she is occupying her time by going to the gym, attending Alcoholics Anonymous (AA) meetings and busying herself in the recording studio.

She added to reporters: "And that’s pretty much my life. And I love it.

"My life now consists of doing things that are bettering, that are going to better myself."

Demi, 23, and Wilmer, 36, announced their break-up over the weekend, and insisted they will remain "best friends".

The ‘Cool for the Summer’ hitmaker posted a picture of their statement on Instagram, which read: "After almost 6 loving and wonderful years together, we have decided to end our relationship.

"This was an incredibly difficult decision for both of us, but we have realized more than anything that we are better as best friends. We will always be supportive of one another. Thank you to everyone who has offered us kindness and support over the years.

"With only love, Wilmer & Demi (sic)."

The news of their break-up came as a surprise as the brunette beauty never rejected the idea of marriage with her former beau.

Speaking previously about tying the knot with Wilmer, she said: "We’ve been together this long … obviously I’m not going anywhere.

"I am very, very in love with him. I think – we will probably wait a little bit longer, but – if he asked tomorrow I would say yes."
