Toni Braxton has resumed touring after being hospitalised due to complications related to her battle with lupus

The 49-year-old star returned to the stage at the Arie Crown Theater in Chicago on Sunday night (16.10.16) and thanked her fans for their support.

She wrote on Twitter: "all TONIGHT at the Arie Crown Theater!!

#TheHitsTour ... I'm heeeerrreeeeee!!! #TheWindyCity ... Hey guys, thanks for all of your well wishes and understanding. I am out of the hospital, and en route to CHICAGO! I can not wait to see you (sic)"

It's the second time Toni has been taken into hospital for complications related to the disease.

The news comes after the R&B superstar expressed how "excited" she was to be able to get back on stage after her first hospitalisation earlier this month.

She said at the time: "I am so excited about going back on the road and seeing all of my wonderful fans and friends.

"Everyone's life is complicated and this is just a condition that I live with."

Toni first revealed she suffers with the potentially life-threatening condition in 2010.

Her uncle previously died from the disease, and her brother is also a carrier.

The 'Unbreak My Heart' singer previously admitted that the hardest part of living with lupus was having to perform, but until this month she prided herself on never having cancelled a show.

She said: "That's the toughest part when I have to perform. So often, when it's like that, it's a lot of, 'You sing!' to the audience, you know. They kind of help me out a little bit without realising it.

"I've never [cancelled a show]. Even if I can't perform, I still figure it out. Sometimes I look back [at] that evening [and] I go, 'How did I get through that?'"

Toni's next concert is at the BancorpSouth Arena in Tupelo, Mississippi on Thursday (20.10.16).
