Is Demi Lovato engaged?

Rumors are swirling that “The X Factor” judge might have secretly gotten engaged after being seen with a rock on her ring finger on Sunday while singing the National Anthem during the World Series game.

According to gossip site HollywoodLife.com, the speculation of Lovato having a finace took to Twitter, where many of her fans wondered if the pop star and Venezuelan/Colombian actor Wilmer Valderrama are now engaged.

Other entertainment publications such as Gossipcop.com claim that the rumor is false after they say they spoke to sources close to Lovato, who confirmed the engagement news are not true.

The news of Lovato supposedly getting engaged with Valderrama comes just weeks after Fox News Latino spoke with Valderrama, who spoke about being single and said he was not involved in a serious relationship.

“I’m a free man,” Valderrama said with a chuckle. “I’m single. I’m not looking, but I'm not closed to the possibility of finding someone special. It will be welcomed.”

Lovato crooned the National Anthem on Sunday,  at Detroit’s Comerica Park, right before the San Francisco Giants defeated the Detroit Tigers.

Looking a bit more conservative than her usual self, Lovato donned black pants, black shirt and a black blazer.

The fans cheered on Lovato, 20, as she sang a flawless rendition of the National Anthem.

This is not the first time the “Give Your Heart a Break” singer takes on the National Anthem.

The singer sang at Game 4 of last fall's World Series Game.
