There have been speculations that singer-actress Demi Lovato and actor Wilmer Valderrama are secretly engaged, and some have said that the couple may be getting married in a secret ceremony, just like Valderrama's "That 70's Show" co-stars Mila Kunis and Ashton Kutcher. But speaking to E! News, Lovato denied that they are engaged. 

"I'm literally turning 23 this week," said the singer on Tuesday, Aug. 18, at the Samsung Galaxy S6 Edge and Galaxy Note 5 launch in West Hollywood. "There's no rush. We've been together so long [that] there's no rush." 

Although they are not engaged, the "Skyscraper" singer said that just like most girls, she certainly has given thought about her future wedding. She revealed that she wants Ed Sheeran to sing at her wedding. She has also browsed Pinterest for ideas for her special day. 

She has often spoken about her boyfriend, and has given him credit for helping her stay sober. In the past, Lovato has struggled with substance abuse and an eating disorder. In an interview with Cosmopolitan, the "Cool for the Summer" hit maker said that she and her boyfriend have split up and gotten back together a few times over the years because of her behavior. 

"The only times we ever broke up were when I was relapsing, whether it was drugs or in a bad place and rebelling against everybody, not just him," she told the magazine. 

Last February, Valderrama denied that they were engaged, but he told E! News that it's something that he "definitely looks forward to in the future." 

Lovato has previously said that if Valderrama proposed to her, she would say yes. Speaking to Extra, the actor said that he is on board with the idea of marriage to the singer. 

"I mean, I'd be more than down," he said about marrying Lovato. "I love her so much."
