Diane Kruger popped in to the Tonight Show Starring Jimmy Fallon studio last night, on the eve of her 38th birthday, and looked glamorous in her white Roland Mouret jumpsuit—with a peekaboo cutout in the back—orange heels, and loose, sexy ponytail. It wasn't the first time she rocked the designer's clothes with colorful kicks: Last month she paired her Roland Mouret separates with dazzlingly bright yellow pumps at the Season 2 premiere of FX's The Bridge.

During the birthday girl's sit-down chat, Fallon surprised her with a red velvet cake and the Season 1 box set of her all-time favorite TV show, The Nanny. Kruger then went on to play a game of Catchphrase with the host, announcer Steve Higgins, and fellow guest Michael Strahan. She warned that she was "really competitive" and she wasn't kidding—during the game, former NFL star Strahan acknowledged Kruger as scarier than any football player he has been around.
