Don’t have a heart attack Lovatics, but Demi Lovato appears to have experienced quite the special weekend.

One day after the “Stone Cold” singer stepped out holding hands with Luke Rockhold outside Madison Square Garden, the famous pair headed to Instagram to post their first pictures together.

Luke kicked things off early Sunday evening when he shared a photo of himself next to Demi at UFC 205.

Demi posted a photo of herself boxing with an unidentifiable individual.

For those who missed Demi’s Saturday night, the “Heart Attack” singer was able to attend UFC 205 with her rumored boyfriend.

While fans may be quick to call this a new romantic relationship, a source shared with E! News last week that Demi is keeping things fairly causal for the moment.

Our insider added, “She thinks Luke is a cool dude and he makes her smile. She is the kind of girl that takes [things] day by day and just lives in the moment.”
