Lady Gaga and fiancé Taylor Kinney have reportedly split up, and fans of the pop star are in mourning.

Gaga and Kinney apparently ended their five-year relationship recently, according to a new TMZ report. The couple was engaged to be married, but speculation abounded when Gaga made several public appearances over the past few weeks without Kinney and without her engagement ring. Kinney had proposed to Gaga on Valentine's Day last year.

Neither Gaga nor Kinney has confirmed the split publicly, though TMZ is reporting that "sources" are claiming they have indeed broken up.

In the wake of this news, Gaga fans all over the world, a.k.a. Little Monsters, have expressed their love toward the pop superstar through the Twitter hashtag #WeLoveYouGaga. Here are some of the best, most powerful tweets about the situation:

Gaga is slated to release her fifth studio album later this year, though a release date (or even a release month) hasn't been confirmed yet. Frequently collaborator and producer RedOne said that the new songs they wrote together have a "classic" and "futuristic" sound to them.

The news of Gaga splitting up is a rare bout of bad news in the middle of what's been a huge year for the singer. At the start of the year she won a Golden Globe for playing The Countess in American Horror Story: Hotel, she sang "The Star-Spangled Banner" at the Super Bowl, she performed an elaborate tribute to David Bowie at the Grammys, and she was nominated for and performed at the Oscars. She also just recently received her driver's license at the age of 30.
