Demi Lovato Engaged To Wilmer Valderrama? Buys Tiffany’s Ring Engraved With ‘With You And By You Always’ For X Factor Judge

Is Demi Lovato engaged to boyfriend Wilmer Valderrama? Reports claim Wilmer Valderrama bought a Tiffany's ring with a loving engraving for Demi Lovato, sparking rumors that the "X Factor" judge and her former "That '70s Show" boyfriend are engaged.

According to RadarOnline.com, Wilmer Valderrama bought Demi Lovato an expensive ring from Tiffany & Co. An insider says Valderrama picked up the Tiffany's ring from a Pasadena, California location on Saturday, Nov. 20.

Wilmer got the ring engraved with the sweet message: "With you and by you always."

This isn't the first time Wilmer has used this phrase with girlfriend Demi Lovato. On August 20, he tweeted: "I've been so proud of the strength & commitment you've gained 4 life, keep inspiring us all! Happy birthday my @ddlovato! With & by u always"

HollywoodLife.com reports that it is a "classic, beautiful" ring and an employee said Wilmer was "really excited and happy" about it.

While it didn't specifically sound like an engagement ring, the source did say, "He chose a really classic, beautiful ring."

"Demi is going to be a happy girl when she gets it. He didn't say what it was for but he was really excited and happy--he seemed like any other guy getting ready to pop the question," she added.

Another source told RadarOnline.com: "It looked like an engagement ring, but could have just been a nice expensive ring he was giving to Demi... He was really low-key at the store and was trying to stay under the radar."

Wilmer, 33, and Demi, 21, split in January 2012, but were spotted out together on numerous occasions in 2013, sparking rumors that they were dating again. The couple celebrated her 21st birthday together at Disneyland in August and then were again spotted holding hands during an Oct. outing to Knott's Berry Farm, RadarOnline.com reports.
