Stars didn’t slow down in the midst of romantic Presidents Day festivities and Valentine’s Day excitement. On Sunday, Ariana Grande and Nicki Minaj lost themselves in the music during their performance at the NBA’s All-Star Game in NYC, which also drew out Jay Z. In other fun moments, Prince Harry hit the slopes, Lady Gaga made her first appearance since getting engaged, and Charlize Theron and Sean Penn brought big smiles to the red carpet.
