Prince's all-female band 3rd Eye Girl have posted a video of the star performing with them in Portugal.

The video, lasting three minutes and 31 seconds, was posted on YouTube on Wednesday (08.01.14) and shows Prince singing his 2010 song 'Cause and Effect' to a huge crowd at Coliseu De Lisboa in Lisbon in August.

The 'Black Sweat' singer, who has been touring with the group, has given an insight into their live shows amid rumours they will head to the UK this year.

The musician and his band are seen bathed in purple light and the audience clap along as Prince sings: ''What we need is compassion, we need love for one another.''

It's one of a three new videos showing the 55-year-old musician playing live, including clips of him performing a show at the Mohegan Sun Arena in Uncasville, Connecticut in December, along with his regular backing band The New Power Generation.

One video also shows his surprise concert in October at his Paisley Park Studios, a $10 million dollar complex built in the suburbs of Chanhassen near Minneapolis, where he performed a career-spanning set.

Prince has been distributing new music with his all-female band via the 3rd Eye Girl website since last year and they embarked on a tour of North America.

According to The Daily Mirror newspaper, the singer is set to bring the band to the UK but he is yet to announce a tour.

It would be the first time the performer has played in the UK since his appearance at the Hop Farm Festival in 2011, and the first time he has played multiple dates since 2007, when he appeared for 21 nights at London's O2 Arena.
