Gaga channeled Hollywood glamour in the glittering jumpsuit, with the cut-out chest detail showing off her assets.
With perfectly styled hair, the 'Bad Romance' singer teamed her sparkly red number with a delicate diamond necklace.
Commenting on one snap posted via Instagram, Gaga said: "I miss my honey pie" with a kiss symbol.
Was Gaga referring to fiancé Taylor Kinney?
The pair got engaged last month on Valentine's Day (14 February).
Gaga later revealed that Taylor first popped the question with a candy ring, before presenting her with the real thing.
Gaga - real name Stefani Joanne Angelina Germanotta - and Chicago Fire actor Taylor met four years ago while filming her 'You and I' music video.
