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.
