Sometimes singers can't contain their emotions on stage. EnStars compiled a list of some performers who broke down during a performance.

1) Selena Gomez: The 21-year-old cried during her performance of Love Will Remember at Brooklyn's Barclay Center on Oct. 16. The heartfelt ballad off her latest album, Stars Dance, was written for her ex-boyfriend Justin Bieber.

"After everything I go through on a daily basis, you guys never fail to make me smile so thank you so much," she told her fans after the song.

Later on that night, Gomez explained the reason for her tears via Instagram.

"Never ended such a beautiful show in tears because they wouldn't allow me to Instagram tonight. Completely heartbroken and pi---d. Thank you SO much Brooklyn. Ill be stopping outside Letterman tomorrow to make it up if you can make it. I love you guys more than you know. Promise," she wrote.

2) Rihanna: The singer broke down on stage during a July concert in France after she performed her song Stay.

"I can't believe this s--t," she told the audience. "You all make me so happy. This is everything that matters to me. And to stand here and feel the love in this room."

She added, "I don't know why the f--k I'm crying. That's crazy. Thank you so much. I love you guys. It's the Diamonds World tour, so you know we can't leave yet."

3) Kelly Rowland: The former Destiny's Child member cried as she sang her emotional ballad, Dirty Laundry, during a May show in Washington D.C. The track addresses Rowland's abusive ex-boyfriend. It also hints at a bit of jealousy towards the success of her former bandmate, Beyonce. It was difficult for Rowland to even finish the song's last few lines because of her tears. Her fans, however, showed support and applauded the 32-year-old.

4) Miley Cyrus: As mascara rolled down her cheeks, Cyrus cried during her performance of Wrecking Ball at the iHeartRadio Music Festival in September. The performance came after Cyrus called off her engagement to Liam Hemsworth.

"I love you," she told her fans. "So there's love right? And there's love and then there's love."

6) Beyonce: The singer performed Etta James' At Last as President Obama and the First Lady took their first dance in 2009. After the song, Beyonce's eyes filled with tears as she received praise from both the President and his wife.
