Pop star Selena Gomez has admitted feeling “extremely unauthentic” and “unconnected” to her music.

The 24-year-old US singer said she needed to “rethink some areas of my life” in a message posted on Instagram after she performed to thousands of fans in Jakarta, Indonesia.

She wrote: “Tonight I felt extremely unauthentic, unconnected to both 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, wholeheartedly?’

“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.”

Selena, a former Disney child star who once famously dated Justin Bieber, posted the message a day after celebrating her 24th birthday.

In the picture caption, she added: “Not being negative about anything I’ve done. I’m grateful for every single moment I get here -Indonesia you were LOUD and clearly inspiring. Love you so much.”

Selena has scored two top 10 hits in the UK – Naturally in 2010 and Come And Get It in 2013.
