Beyonce Knowles set to tour with Solange

Beyonce Knowles is reportedly set to be accompanied by her younger sister Solange on her world tour.

The former Destiny's Child singer – who will perform in countries including America, Canada, Mexico, Japan, Africa, Australia and various locations around Europe to promote her upcoming album 'I Am… Sasha Fierce' – will be joined on the road by her 22-year-old sibling.

A tour insider said: "Discussions are underway for Solange to join Beyonce on her tour.

People who buy tickets for Beyonce's show can then go and see Solange perform at an official after-party."

Beyonce will embark on the 110-date world tour next April.

The 27-year-old singer recently revealed the inspiration behind the name of her new record is her on-stage persona, Sasha.

She said: "I have someone else that takes over when it's time for me to work and when I'm on stage, this alter-ego that I've created that kind of protects me and who I really am.

"Sasha Fierce is the fun, more sensual, more aggressive, more outspoken side and more glamorous side that comes out when I'm working and when I'm on the stage."

'I Am… Sasha Fierce' will be released worldwide next month.
