Justin Timberlake enjoyed a night out at Guy Ritchie's London pub The Punchbowl on Monday (29.06.09), teaming up with the director for an impromptu music session.
Justin Timberlake jammed with Guy Ritchie on Monday night (29.06.09).
The 28-year-old singer rushed to Madonna's ex-husband's London pub The Punchbowl after enjoying a late dinner at The Wolseley.
After greeting each other with a hug, the pair - who became friends when Justin worked with Madonna on hit single '4 Minutes' - downed pints of lager, before dusting off a banjo and a guitar and belting out a few songs.
An onlooker said: "Justin got there about 11.30pm. Guy had been there since 8pm and the night quickly got very merry. At one point they were in such high spirits, Guy picked up a banjo and handed Justin a guitar and they had a little singsong."
Justin - who is dating actress Jessica Biel - left the pub at around 1am, and headed to a private party in Mayfair, before returning to his hotel at 2.30am.
Justin has been linked with starring in a tribute concert to Michael Jackson - who died of a suspected cardiac arrest last Thursday (25.06.09) - but admits he would be "cautious" about taking part.
The 'SexyBack' singer told London's Evening Standard newspaper: "It is extremely tragic - there really was only king. It's an honour to be considered for a tribute to the greatest of all time but also there is a level of just me as a fan that would feel very cautious about doing something like that.
"Like anyone else in the world I'm his biggest fan. I just feel like if there would be any pretension, it would not be good. That's my worry. I understand tributing somebody who is so influential to every artist of our generation. It would have to be done properly."
Concert promoters AEG are said to be trying to organise a series of concerts to fill some of the dates allocated for Jackson's 50-date residency at London's O2 Arena, which was due to begin later this month.
In addition to the 'Like I Love You' star, they are also reportedly trying to recruit Diana Ross and Ne-Yo. |
