For the 'Video Phone' clip, Beyonce asked a very famous friend to co-star: Lady Gaga. And while the beginning of the stylish video pays homage to Quentin Tarantino's 1992 film 'Reservoir Dogs,' Mother Monster spent her time on the shoot paying tribute to someone else -- Beyonce herself.

Calling herself Gee-yonce, Gaga dressed the same way Bey did, and asked that their hair and make-up be done similarly as well. In a later interview, Gaga explained, "Neither of us had an ego. It wasn't about competition. It was ... 'Let's do a real girl-power collaboration where we support one another.'"

Whatever they did, it worked. 'Video Phone' won Video of the Year at the 2010 BET Awards.
