While most of Hollywood went east for the 2013 VMAs, Demi Lovato, who has said she avoids the party atmosphere so that she isn't tempted, spent Sunday, Aug. 25 at Disneyland in Anaheim, Calif. She did so with her on-off BF, actor Wilmer Valderrama. It was a belated bday celebration.

Lovato, Valderrama and some pals were seen noshing on some park eats, and Lovato even wore a silver pair of Mickey Mouse ears. She is a former Disney star, so it was only fitting. We wonder if she got a discount.

Valderrama tweeted at Lovato on her actual birthday, Aug. 20. It was sweet and certainly suggested that they may be back on.

Since Lovato was out of the country and in Africa on her actual birthday, she had to wait a few days to celebrate domestically.

A source told Hollywood Life that due to the singer's work schedule with 'X Factor,' she decided to use one of her "free" days "to see people she hasn’t seen in a bit and hang out with Wilmer. She wanted to go to Disney and enjoy the rides and just have a fun birthday with people she was unable to hang out with when she was in Africa."

The source said that the hang was fun-filled, revealing, "They did everything you can do at Disney — they enjoyed the parades and they spent a majority of their time in Cars Land and the Tower of Terror areas, which they were really happy with. It was a nice and enjoyable day out. A lot of laughs and a lot of fun were had. It was a good birthday."

Happy 21st once again, Demi.
