Sinead O’Connor operated on by a robot

Sinead O’Connor has had an operation performed by a robot.

The singer took to social media on Friday morning to announce to followers that she is to have surgery.

The 49-year-old updated her status on the site to say: ‘Tomorrow I’m having surgery performed by a robot!’

The Nothing Compares 2 You singer has worried fans in the past few months with unusual posts on her social media.

Fans were again concerned for her after she posted about going under the knife, wishing her a speedy recovery from the unknown operation.

The singer hit the headlines earlier in the year when she was reported missing in Chicago last May. She was later found safe.

Sinead previously underwent surgery for her health last year when she had part of her womb removed in a hysterectomy.

The controversial mother-of-four has been in and out of the public eye since rising to fame in the 1980’s.
