Britney Spears still misses Michael Jackson.

The 'Till the World Ends' singer, 31, paid a touching tribute to the late King of Pop on the fourth anniversary of his death on Tuesday (25.06.13), and said it was an honour to once perform a duet with him.

The blonde beauty wrote on Twitter: ''My thoughts are with the Jackson family today. Honoured to have shared a stage with him. Miss u Michael!''

She also posted a picture of the pair performing 'The Way You Make Me Feel' for Michael's 30th Anniversary Celebration in 2001.

Following his death from Propofol intoxication in 2009, Britney admitted she was devastated.

She said: ''He has been an inspiration throughout my entire life and I'm devastated he's gone!''

Meanwhile, Michael's daughter Paris Jackson is set to remain under the care of her grandmother Katherine Jackson and cousin TJ following her recent suicide attempt.

A judge has decided that the 15-year-old aspiring actress, who is still in hospital in Los Angeles, will remain in their care after an investigation by a probate court but her biological mother Debbie Rowe has allegedly made it clear that she will mount a custody challenge if necessary.

A source told gossip website TMZ.com that Debbie believes the current situation is working out well but she will file for legal guardianship if it gets worse.
