Demi Lovato and boyfriend Luke Rockhold are spending more time together. Reportedly, Demi likes being around Luke, as she just got out from a serious relationship with Wilmer Valderrama. But their romance is not blooming in the way it supposed to be. Who is coming between lovebirds? It's none other than singer, songwriter- Taylor Swift.

According to Hollywood Life, despite being spotted on so many sexy date nights with Demi, Luke seems to have a major crush on one of Demi's frenemies - Taylor Swift.  

Few days back the 24-year-old singer, Lovato and 32-year-old former UFC fighter, Rockhold have been spotted attending a Los Angeles Rams football game happily, E! News reports.

The couple have also been sending secret messages to each other via social media. Before Luke, Demi had six years of serious relationship with Wilmer Valderrama. They broke-up because Demi wanted to take their relationship to next level but Valderrama was not ready to commit.

According to few sources, Luke has had a crush on Taylor for years, as he is very much interested to date super sexy singer. Luke also follows Taylor on Twitter.

Last year during "Millionaire Matchmaker" in 2015 show, Luke had been caught lewd and making incredibly vulgar comments about woman. In a clip from the show that recently resurfaced, Luke questioned a contestant about her oral sex habits! He asked, "Would you rather swallow or spit, girl?" Seriously? So, vulgar! The poor girl was unnerved and shocked, and told him that question is "inappropriate." For this incredibly lewd and disrespectful question, Luke was kicked out of the show.

Does Demi have any idea about it? should Demi be worried about Luke's lewd comments? She certainly needs to be careful while going forward her relationship with Luke.

The reality TV Star  comes into the Ultimate Fighting Championship in early 2013 after the Strikeforce organization was closed. He won the UFC Middleweight Championship on December 12, 2015.

What does Taylor will think of Luke's crush on her? Only time will tell.
