Demi Lovato and Wilmer Valderrma have rekindled their romance and are looking to take their relationship to the next level, as reports have surfaced he purchased an engagement ring for the X-Factor judge. 

According to Radar Online, the That 70's Show actor purchased the jewel from Tiffany & Co. in Pasadena, Calif on Nov. 20 and even had it engraved with the special message, "With you and by you always."

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

The couple celebrated her 21st birthday together at Disneyland in August and then were spotted holding hands in October when they went to Knott's Berry Farm. 

Meanwhile, Lovato spoke with Miami's Y100 radio backstage at Jingle Ball 2013 and was forced to answer an unexpected question. 

She picked a question out of the Santa hat that read: "You were picked to give one celebrity plastic surgery. Who would it be and what type of surgery?" Though she first refused to answer, saying, "I shouldn't even think this," Lovato then jokingly replied: "It should be me! I should get a boob job. They're like mosquito bites."

Back in September 2012, Lovato revealed to Katie Couric that she struggled with body image issues when she was young. 

"When I started having body image issues I remember being three years old in a diaper and rubbing my hand over my stomach ... and I remember thinking in my head 'I wonder if one day this will ever be flat?'" she said.
