Katy Perry is having a very good start to 2015.

Not only are Perry, 30, and John Mayer, 37, officially a couple once again, she also is preparing to wow the world, along with Lenny Kravitz, at this year’s Superbowl halftime show.

Nearly a year after breaking up, the Firework singer and Mayer stunned A-list stars when they made a dramatic entrance together on Thursday at Hollywood hot spot the Tower Bar, according to Page Six.

“Katy Perry and John Mayer walked in together, arm in arm, and the whole room literally fell silent,” an insider told the newspaper, which reported that the couple frequented the restaurant on a regular basis when they were previously dating.

“Even Dimitri Dimitrov — Hollywood’s most famous maitre d’, who has seen everything — and Sunset Tower owner Jeff Klein both stopped mid-sentence when John and Katy arrived, as if they wanted to announce to everyone in Hollywood they are back together,” said the source.

It was a busy night at the Tower Bar, according to Page Six. Director and producer Lee Daniels was having dinner at a nearby table with Naomi Campbell. At another table were American Sniper director Clint Eastwood, with a table of powerful Hollywood producers. Liz Goldwyn was spotted with Dita Von Teese, and Kid Cudi was dining with Bryan Greenberg and Jamie Chung.
