While getting ready for the 58th annual Grammy Awards Monday night, Taylor Swift and Selena Gomez had a full-blown freak out when they found out "Bad Blood" won the Grammy for Best Music Video.

The two were filmed in a dressing room shaking and screaming when the announcement was made a few hours before the live telecast. "'Bad Blood' just won a Grammy for Best Music Video and we are not ok. @selenagomez," she wrote on Twitter.

"I got to be in my best friends [sic] first Grammy award winning music video!!!!!!?! #Grammy9 @taylorswift13," Selena retweeted.

Ahead of music's biggest night, it was also unveiled that Taylor's 1989 project won a Grammy for Best Pop Vocal Album. The ceremony, hosted by LL Cool J, will broadcast live from the Staples Center in Los Angeles at 5 p.m. PT on CBS.
