Melbourne, December 3 : Britney Spears, who turned 27 on December 2, heard the ‘World’s Sexiest Man’ Hugh Jackman sing ‘Happy Birthday’ for her before the singer blew out the candles on the cake.

The ‘Toxic’ hit maker received Jackman’s wishes, who also blew her a kiss, in a recorded video message after her live performance on ‘Good Morning America’ in New York – despite not having met the actor ever.

Britney entertained the crowd with two of her songs, including ‘Womanizer’, from her latest album ‘Circus’ in an elaborate tent with a ring of fire, dressed as a ringmaster, reports the News. com. au.

The pop star was also wished by the cast of Desperate Housewives, Reese Witherspoon and John Travolta in pre-recorded messages and was said to have been touched by their greetings.

The singer further revealed during the show the dates of her forthcoming 27-city world tour that is set to begin in her native Louisiana on March 3, 2009. (ANI)
