When Rosie O'Donnell took a job at OWN, we bet she never thought she'd be doing tequila shots with network CEO Oprah Winfrey. But at a party for 'The Rosie Show,' the pair knocked a few back and the results were, luckily for us, televised in a recent 'Rosie' episode.

So which diva holds her booze best? Winfrey managed to take the shot without complaint, but O'Donnell howled as it burned her throat. Lightweight!
