Pop singer Janet Jackson has revived the spirit of her late brother Michael on stage with a virtual duet, two years after the King of Pop's death.
The singer took her Number Ones: Up Close & Personal Tour to London's Royal Albert Hall on Thursday where she served up a career-spanning set of her hits.
Opening the show with the video of her 1980s electro funk Nasty, she treated fans to a virtual collaboration with Michael on their 1995 hit Scream.
While she performed her part of the single, her older brother's vocals were played for his section of the song and a video of him was played on screen.
"It's therapeutic, you know and it makes me smile inside," Jackson told British radio.
"I mean the energy of the song is fierce but it makes me smile inside when I hear him, when I hear his voice."
It was the two-year anniversary of the Thriller singer's death last Saturday.
He died age 50, on June 25, 2009 at his rented mansion in Los Angeles, as he was rehearsing for a series of London concerts.
Authorities said he died of a massive dose of the anesthetic propofol and a cocktail of other sedatives and painkillers.
Paying tribute to her brother at the end of her show, Jackson flashed childhood pictures of the siblings on a screen while she performed her song Together Again.
In her first tour in three years, the Grammy award winner performed songs from her Number Ones album, featuring 35 number one hits.
Known for her high energy and well-choreographed routines, she danced her way through What Have You Done for Me Lately, Control and raised the heat with a live version of Nasty.
Having infamously bared a breast after a "wardrobe malfunction" at the 2004 Super Bowl, Jackson was fully covered on Thursday, starting the show in a white jacket and trousers, worn with white high-heeled boots.
She later changed into a vest and jeans, accessorised with diamante braces that hung below her waist.
The tour, which sees her play three shows in London, will be performed in 35 cities.
