Robbie Williams headlined the Capital FM Summertime Ball at Wembley Stadium on Sunday, and he was joined by acts including Taylor Swift.
Robbie Williams has launched a tirade against Britpop stars Suede as he took aim at the group's frontman Brett Anderson.
Gary Barlow has been honoured with the Music Industry Trust Award at a prestigious bash in central London.
Robbie Williams has released an expletive-ridden track attacking this year’s “boring” Brit Awards.
The 17-time Brit Award winner raps, "Well that Brits night was so f****** boring", before recalling some of the wilder antics at the event when he was younger - taking drugs, challenging Liam Gallagher to a fight and having sex with "a few female stars or two".
The former Take That star posted the track, titled "THE BRITS 2013", on his website, telling fans, "Here's a gift from me and Guy - we wrote it on Saturday, recorded it on Sunday".
"Guy" is Guy Chambers, his long-running song-writing partner who he has patched up differences with and the pair are now working on new material.
But he warns them it is not suitable for younger listeners. "If you have kids in the room, don't play it," he wrote.
Williams performed his No. 1 hit Candy at last week's event at the O2 Arena, which many critics labelled as bland and uneventful.
Television bosses want the duo to provide "fireworks" on the talent show and are planning on bringing back Nicole Scherzinger as a judge, The Sun reports.
The popstar pair fell out when Williams quit Take That in 1995 but have since made-up when the Angels and Rock DJ singer rejoined his bandmates in 2010 for a new album and string of sell-out concert dates.
A spokesman for the show said: "It's far too early to say anything about the judging panel for this year's X Factor."
Robbie Williams has teased fans with the prospect of another reunion with Take That pal Gary Barlow after posting a picture online of the two of them rehearsing.
The duo are seen singing on a podium together surrounded by musicians in the image which was posted on Twitter earlier today, sparking speculation they will perform in the next few days.
The photo is accompanied by the caption: "Robbie and the Captain - what are they up to?"
Williams was reunited with his erstwhile bandmate earlier this month when they teamed up as Barlow was celebrated with a Music Industry Trusts Award at a gala dinner.
Both performers are due to play solo shows in the coming days. Williams is on the bill for the Royal Variety Performance on Monday and will play headline shows at London's O2 Arena from Thursday.
X Factor judge Barlow is to perform a Little Noise Sessions show for Mencap on Monday at east London's St John-at-Hackney Church, and is also playing a series of shows throughout this month and through to January as part of his first solo tour for 13 years.
