Kristen Stewart and Taylor Lautner reunited at the Los Angeles premiere of American Ultra on Tuesday.

The 25-year-old actress and 23-year-old actor walked the red carpet together at The Theatre at the Ace Hotel. Stewart and Lautner co-starred as Bella Swan and Jacob Black, respectively, in the Twilight series of films.

The actress was all smiles in a floral, sequined Zuhair Murad romper, while Lauter kept things casual with a navy jacket, white tee and black pants. The friends and former co-stars were last spotted together at a Sam Smith concert in January.

Stewart was also photographed with American Ultra co-stars Jesse Eisenberg, John Leguizamo and Connie Britton. The film stars Eisenberg as a stoner sleeper agent who must protect himself and his girlfriend (Stewart) after he is activated by the government, and opens in theaters Friday.

The actress and Lautner co-starred in five Twilight movies, including the fifth and final film The Twilight Saga: Breaking Dawn - Part 2 (2012). Stewart went on to appear in such films as Clouds of Sils Maria and Still Alice, while Lautner played Dale on BBC Three series Cuckoo.
