Grammy winner and popular Christian singer–songwriter Tori Kelly has been hospitalised after collapsing at a restaurant in Los Angeles.

According to TMZ, the singer, who rose to fame on YouTube, is currently being treated at Cedars-Sinai Medical Centre for multiple blood clots around her vital organs. The 30-year olds condition is thought to be "really serious".

Kelly and her team have yet to give a public update on her health.

Fans have taken to social media to offer prayers, scripture and support for the singer. One user said on Instagram: "praying for a miraculous healing. We believe in a God who heals and I am praying and believing he will work on his child and heal every inch of your being."

Another said: "I know the power that prayer has and I'm praying hard for you!!"

Speaking in an interview last year with "Switch", the youth ministry for US mega-church Life.Church , Kelly opened up about her belief in God and her conviction to put Jesus first in her life, remarking that her "faith is everything" to her.

The star, who has collaborated with Ed Sheeran, Justin Timberlake and Pharrell Williams, won two Grammy Awards in 2019 - Best Gospel Album and Best Gospel Performance/Song.

Her new EP 'tori' is expected to be released on 28th July.
