Celebrating: Lady Gaga kept the party going after the Grammy Awards on Sunday night with Mark Ronson, joining him at his Club Heartbreak Grammy Party, sponsored by Absolut Elyx

Following her rather demure – by her standards – outfit on the red carpet earlier in the evening, Gaga pulled out all the stops for the after-party.

She let loose as she celebrated long into the night, opting for a far more out there look for the bash.

Gaga striped down to her black lingerie, which she teamed with a sequin jacket and bibi hat from the Celine by Hedi Slimane Spring/Summer 2019 collection.

She topped off the look with a sparkling silver choker necklace and some serious attitude.

The off-the-shoulder number boasted bow detailing at the bust in a contrasting black satin, ballooning out at the arms.

Mark and his fellow revelers were seen dancing the night away as they sipped on cocktails and enjoyed some good tunes.

Earlier in the evening, the star performed her hit at the Staples Center in Los Angeles.

She turned up the tempo for the ballad – which won a BAFTA earlier in the day – as she slayed the song and the stage in a bejeweled catsuit.

Daring to impress, the Born This Way Songstress gave her fans a charge as the futuristic ensemble featured a plunging design.

Superstar: Earlier in the evening, Gaga reminded us she’s a true music sensation at the Grammys on Sunday

Dazzling: She had walked the red carpet in a silver sequinned gown with a ruffle down one side, the custom Celine by Hedi Slimane dress marking one of her most demure awards show looks to date

Her flawless figure was thrust on center stage as the one-of-a-kind body suit fit her form tightly.

The song is usually performed in a reserved manner, but Gaga kicked it up a notch as she commanded the stage with kicks, hair flips, and animated faces.

She slithered up to Mark Ronson – one of the song’s co-writers – as she wailed in a guitar for the jam session.

Slayed: And Gaga turned up the tempo for the ballad – which won a BAFTA earlier in the day – as she slayed the song and the stage in a bejeweled catsuit

Perhaps the artist’s high energy levels came from the three Grammy trophies she won before the performance.

Gaga won Song Written for Visual Media and Best Pop/Duo Performance for Shallow,’ and Best Pop Solo Performance with Joanne (Where Do You Think You’re Goin’?).

She even took home a BAFTA earlier in the day for Shallow, which Bradley Cooper scooped up at the show in London.

And then another triumph, this time for Gaga alone, as she was named best pop solo performance for Joanne (Where Do You Think You’re Goin’?).

‘A Grammy for Joanne is more than me & my family could ever dream of. I sang that version in one take, & poured my entire life & soul into it. Thank you so much for this gift I am completely shocked. 2nd Grammy win of the night I am so overwhelmed by this kindness.’
