Selena Gomez is having a very emotional birthday weekend.

The "Hands to Myself" singer, who turned 24 on Friday, celebrated the occasion by kicking off the international leg of her Revival tour in Jakarta, Indonesia.

While talking to the crowd, Gomez got a little teary-eyed just moments before she performed "Kill 'Em With Kindness."

"The next song, before I go home, is a song that's so important to me," she said onstage, wiping away tears. "Because I get really frustrated, I get stupid sometimes, I say things that I don't mean. Or that come out wrong just because I care so badly."

"But the thing is, at the end of the day, no war in anger was ever won," she continued. "I do know that deep down in my heart that I have to believe that we can love each other and always be kind no matter what it takes in us. I believe that we can do that, no matter what."

Following her show on Saturday, she took to Instagram to post a cryptic message to her fans. "Not being negative about anything I've done," she explained in the caption. "I'm grateful for every single moment I get here -- Indonesia you were LOUD and clearly inspiring. Love you so much."

The accompanying picture was a screenshot of a message she wrote up using her iPhone's notes app:

"Tonight I felt extremely unauthentic, unconnected to both my myself and my music. I've never really felt like my materials, wardrobe or a video could define me. I act on a moment and fear something that hasn't happened. I'm stagnant, I stay still and don't just sit with myself first and ask, 'Is this where I am, whole heartedly?' I've always told the truth. I'm always true to my word, I've shown who I am but I need to rethink some areas of my life creatively and personally. Had to get that out."

All of this comes a week after Gomez received backlash for defending her close friend, Taylor Swift. As previously reported, Kim Kardashian leaked a phone conversation between the pop star and Kanye West over his controversial "Famous" lyrics via Snapchat. Within minutes of hearing Swift approve West's "For all of my Southside n***as that know me best, I feel like me and Taylor might still have sex" line, which she previously denied doing, fans hopped on Twitter and the hashtag "#KimExposedTaylorParty" began trending.

Gomez weighed in, writing, "There are more important things to talk about. Why can't people use their voice for something that f**king matters?"

"Truth is last thing we need right now is hate, in any form," she added. "This industry is so disappointing yet the most influential smh."

Her tweets resulted in the creation of another trending topic that night -- "#SelenaGomezIsOverParty."

While Gomez didn't specifically address what her comments onstage or over Instagram were referring to, it's hard to imagine that harsh hashtag didn't have something to do with her emotional demeanor. To hear more on the West-Swift feud, watch the video below.
