The singer, nominated for best actress for A Star Is Born, wore a strapless lavender couture Valentino gown similar to one her predecessor wore in the film.
The singer stole the show as she arrived in a strapless lavender couture Valentino gown with voluminous sleeves.
Viewers watching at home were reminded of her A Star Is Born predecessor Judy Garland, who wears a similar dress in her version of the film.
Gaga is nominated for best actress in a drama for her role as pop star Ally in the modern version of the story, directed by and co-starring Bradley Cooper.
Garland starred in the 1954 version alongside James Mason and wore a full lavender gown complete with elbow-length gloves and a bolero jacket.
The role of Ally is Gaga's first leading role in a film and the singer said creating the character was very different to those she has created in her performing career.
