The Golden Globe Awards swept through LA on Sunday night and reunited plenty of stars with their former costars. Big Little Lies' Shailene Woodley, Reese Witherspoon, Nicole Kidman, Laura Dern, and Zoë Kravitz found themselves together again at the glamorous ceremony, while the cast of Euphoria partied the night away at the annual Warner Bros. and InStyle bash. But that wasn't all! Nina Dobrev, Ian Somerhalder, and Paul Wesley came together almost three years after The Vampire Diaries' finale, and One Tree Hill's Sophia Bush, Danneel Ackles, and Bryan Greenberg made our hearts skip a beat when they posed together for a fun elevator video. See all the exciting reunions ahead!
