Just before taking the stage, the "Heart Attack" songstress opened up about her relationship with Wilmer to ET Correspondent Lance Bass."Wilmer is one of the most incredible people on the planet," she gushed.But Demi Lovato was not so willing to give Wilmer Valderrama's harsh critics a break, taking to Twitter on Wednesday to lash out at a news site for slamming her boyfriend as 'culturally irrelevant' with a 'flagrant lack of modesty.''Gonna give my hair a breeaaakkk, give my hair a break, gonna give my hair a break, my hair a break...
The fact that they had been together for such a long time seemed to convince Demi that Wilmer was the one she wanted to spend the rest of her life with.
In fact, Wilmer is the one who suggested that Demi and Joe reunite for a Camp Rock reunion duet at her show in Los Angeles last month.
Demi also showed-off her edgy new hairstyle during her VEVO performance, a bob-style cut with one shaved side and teal-blue ends.
Demi Lovato performed a slew of hits at the Vevo Certified Super Fan Fest in Los Angeles on Wednesday night.
The concert, presented By Honda, also featured a performance by "Fancy" singer, Iggy Azalea.
