Birthday suit: What Lady Gaga did not wear...

Lady Gaga celebrated her 28th birthday with an energetic but short concert at the Roseland Ballroom in her first of seven concerts at the closing venue.

Gaga performed for an hour Friday night in front of a feverish crowd. She started with a slow version of "Born This Way" on piano, with the audience joining in. She followed that with the jams "Monster" and "Bad Romance."

She danced and sang on the side of the stage in a red tight leotard and a green-yellow wig.

Gaga was in top form as she sang nearly a dozen of her songs, including "Just Dance," an acoustic version of "Poker Face," and the recent hit "Applause." The concert's main surprise: It was too short. After she ended, fans waited for the pop star to hit the stage again. She never did.

She performed some tracks from her recent album, "ARTPOP," which has struggled to match the success of her other releases. But onstage, she showed no signs of slowing down.

The singer then grabbed eyeballs when she turned up in a nude coloured bodysuit for her 28th birthday party.

She arrived at Roseland Ballroom Theater here Friday wearing a nude coloured sheer bodysuit, reports entertainmentwise.com.

The outfit was completely see-through, but red roses were strategically placed to cover her body parts.

Her face was covered with a red veil and she made sure to wave out to her fans.

She teamed up the outfit with pink platform super-high heels.

Gaga arrived at Roseland Ballroom on March 28 covered head-to-toe in furry white pieces, including a complete face mask.

The other fringed items consisted of a loose sleeveless dress and knee-high boots.

Amid the awkward get-up, the Do What U Want hitmaker seemed proud, waving at onlookers.

Though, it's unclear as to how she managed to see through her shaggy mask.
