Demi Lovato Engaged: Diamond Ring Sparks Rumors Singer Is Engaged (UPDATE) (PHOTOS, VIDEO)

Demi Lovato wowed the crowd as she sang the National Anthem at opening game four of the World Series on Oct. 28, but it was the bling on her ring finger that sparked some rumors.

The 20-year-old singer and "X Factor" judge was spotted wearing a diamond ring on her left hand, which could only mean one thing -- she's engaged. Well, probably not, but Twitter sure likes to gossip.

Demi's diamond caught the attention of some fans, who started wondering if the singer is secretly engaged to on-again, off-again boyfriend Wilmer Valderrama, reports HollywoodLife:

Speculation from fans isn't enough to convince us that Lovato is engaged, plus we're not even sure whom she is dating right now. Earlier this month the "Skyscraper" singer basically admitted she had been casually seeing One Direction's Niall Horan, but the casual couple might already be over. According to Perez Hilton, the boy band member is now dating a drama student named Amy Green.

UPDATE: When asked for comment, Lovato's rep told The Huffington Post, "No, there is no truth to [these rumors]."
