She’s known for courting attention with her outlandish outfits.

But Lady Gaga kept her stylists well and truly on their toes on Wednesday as she sported four different outfits in just one day.

The most revealing ensemble, however, came when Gaga headed to a performance on the Late Show With David Letterman in New York wearing a revealing bra, black panties, fishnet stockings and towering platforms.

What’s that? It was the ring on Gaga’s left hand that courted the most attention

To fend off the Manhattan chill the 28-year-old covered up just slightly with a black motorcycle jacket.

She donned an enormous chartreuse bouffant wig with a full face of make-up which was slightly obscured behind a pair of black sunglasses.

Looking like a cross between Married With Children’s Peg Bundy and Sandy from Grease, the eccentric artist created quite the spectacle as she taped her segment with David Letterman.

But it wasn’t Gaga’s sartorial choices that courted the most attention.

Instead, all eyes were drawn to the diamond ring Gaga was sporting on her left hand as she signed autographs for fans.

The design featured a gold band and a diamond bow detail – a less traditional kind of engagement ring, but one suited to a singer as eccentric as Gaga.

Easy does it: She negotiated the sidewalk in her towering platforms

Helping hand: Gaga, Bill Murray and Letterman all skipped along together

It remains to be seen whether or not Gaga is engaged – and what she would wear down the aisle – but she has been in a relationship with actor Taylor Kinney since 2011.

Speaking previously about their romance, Taylor said: ‘For whatever reason it just works … and that’s that.’

MailOnline has contacted a spokesperson for Gaga for comment on the engagement reports.

With a big smile across his face, the 66-year-old held Lady Gaga’s hand as they walked passed the throngs of fans.

At another point, she and Dave were joined by actor Bill Murray.

The 63-year-old also grabbed a hold of one of the singer’s hands and three made their way down the barricaded street.

Just another day: Dave wore a classic navy blue suit which balanced Lady Gaga’s more absurd attire

After her appearance on the late-night show, she changed into a different ensemble consisting of a conservative pale pink chiffon trench, long brown wig and a classic black tote in her right hand.

Her understated glamour was a welcome change from her usual theatrics.

Earlier in the day, Gaga emerged from a New York City rose-adorned taxi cab wearing a floral mini dress which displayed her slender legs in slightly more demure fashion.

The ArtPop hitmaker is currently in the middle of a seven-night residency at Roseland Ballroom, which will end with the closing of the legendary New York venue.

The residency ends April 7, and she’ll later kick off her ARTPOP Ball Tour May 4 at Florida’s BB&T Center in Ft. Lauderdale.

The 52nd Street theatre is closing its doors after 56 years, and the G.U.Y. singer is the final performer to take the stage.

‘It’s basically the only room in the city I haven’t played,’ Gaga told The New Yorker earlier this week, noting that Manhattan clubs are ‘where I learned to be bold.’

The Roseland Ballroom will eventually be transformed into a 59-storey residential tower.
