Talk about friends in high places.

Usher, who turned 34 on Sunday, celebrated his birthday over the weekend in the company of Hollywood royalty. Dining at Scott's Restaurant in Mayfair, London, the night before his big day, the multiplatinum R&B singer Instagrammed a photo of himself sandwiched between pals Tom Cruise and Sir Ridley Scott, the Oscar-nominated director of films including Gladiator and Alien

"Just an average pre-birthday for @Howuseeit...thank you Tom and Ridley for dinner lots of laughs and good conversation," he tweeted, referring to his Instagram username.

The "Scream" singer has had a busy few months.

On August 24, after a heated legal battle with ex-wife Tameka Foster, the star was awarded primary custody of his sons Usher Raymond V, 4, and Naviyd Raymond, 3. As a result, he decided to postpone his Euphoria tour, originally slated to kick off in January, until next fall. He plans to use the time off to focus on his kids.

"I truly appreciate and am grateful for your support while I take this time to focus on my children and continue to evolve with my fans," he said in a statement on his website. "Evolve or evaporate."

As part of that evolution, the chart-topper will also be prepping for his role as a mentor on season 4 of The Voice. NBC recently announced that Usher and Latin singer Shakira, 35, would join the show as replacements for Cee Lo Green, 38, and Christina Aguilera, 31.
