Rihanna celebrated her brother’s graduation on Thursday night with a classy supper at the Mamo Italian restaurant in New York, showcasing her sophisticated sense of style.

The singer, 36, arrived arm in arm for the party with her stylish boyfriend A$AP Rocky. They wore matching translucent dresses and a plunging leather blazer.

Rihanna paired the stylish black jacket with the matching sheer black midi dress, showcasing her tiny waist.

The outfit included a sheer skirt with an adorable frilled velvet accent, and Rihanna accessorized her ensemble with matching high heels.

Adding a black leather handbag with a pattern to her suit, Rihanna brought some brightness to the otherwise somber ensemble with her vivid blond hair.

Rocky and Rihanna showed off their stylish sense of style when they came at the graduation party carrying gifts. Rocky was dressed in a dapper pale blue suit.

Riot Rose, who is nine months old, and RZA, who is two, were not with the pair.

On Monday, Rihanna and Rocky celebrated RZA’s second birthday and shared a joyful Instagram photo to let the world know their little baby was growing up.

Rocky wrote a lovely picture of himself holding the birthday boy upside down, “HAPPIEST BIRTHDAY 2 MY 1ST BORN BABY BOY RZA,” while Rihanna carried Riot Rose upright and grinned sweetly.

After welcoming two little boys, the two parents seemed closer than ever. In fact, they have been spotted together and looking smitten several times in the past several months.

People was told earlier this month by a source that Rihanna and her lover, Rakim Athelaston Mayers, ‘had always had a great relationship and the romance really improved that.’

They also mentioned that the couple’s “family comes first.”

Another source stated that Rihanna ‘loves’ her two children and that she ‘is all about motherhood’.
