Prague, Czech Republic ? Rolling Stones fans hoping for a glimpse of Mick Jagger’s 60th birthday bash in Prague this weekend can’t get no satisfaction.

The Stones frontman celebrates his birthday today at a secret party in the Czech capital, where the Stones perform Sunday as part of their “Licks” world tour.

The party venue remains a closely guarded secret. Local media have speculated Jagger will celebrate at the British Embassy in Prague’s Thun Palace or at the Four Seasons Hotel.

Even former President Vaclav Havel, an invited guest, does not know where the bash will be.

“We will be told at the last minute,” said Havel’s aide, Martin Vidlak. “This is a private party under full control of Mick Jagger.”

Although the party venue remains secret, word of Havel’s birthday present to Jagger has been leaked to the press: a 2-foot-high crystal vase by Havel’s favorite artist, Borek Sipek.
