Lady Gaga Goes Bra-less As She Arrives With Tony Bennett For Cheek To Cheek Performance In New York

She certainly knows how to make an entrance.

On Monday, Lady Gaga accompanied crooner Tony Bennett to a joint performance in New York City wearing a slinky black ensemble with a very plunging neckline.

The Applause singer made quite the dramatic departure from her usual quirky wear as she arrived hand-in-hand with the 87-year-old for their live performance of Tony Bennett & Lady Gaga: Cheek To Cheek Live at the Lincoln Center.

Cheek To Cheek is the pair's upcoming duet jazz album, and the pair will perform selected tracks at the Lincoln Center for a TV special that will eventually air on PBS on October 24, according to ABC.

The singers previously teamed up together in 2011 for the jazzy single, The Lady Is A Tramp.

And on Monday, the pair looked quite chummy as they arrived together for their hotly anticipated duet.

Gaga ditched her dramatic wigs and sequined ensembles for a classy black dress featuring a silver neck and waistline that nipped at her midsection.

She pulled her hair up into a taut bun, and kept the make-up to a comparative minimum with a coat of smokey shadow to accentuate her lovely eyes.

As for Tony, the Fly Me To The Moon singer looked every bit the seasoned professional in his crisp black tuxedo featuring a red pocket square.

Later, Gaga planted a tender peck upon Tony's cheek, who couldn't resist letting out a grin.

Certainly not one to miss out on the performance were Lady Gaga's proud parents, Joe and Cynthia Germanotta.

Cynthia glammed up her all-black frock with a layered pearl necklace, while Joe looked sharp in his polished tuxedo featuring a shiny tie.

And though the pair's duet record has seen their release date pushed back several times, fans can likely get their hands on Cheek To Cheek in September, according to Showbiz411.
