Kat out-dances her fellow housemates

After an emotionally hard day, Kat's spirits were visibly lifted as she enjoyed the party and silent disco provided by Big Brother tonight.

Kat jumped around with her arms in the air for over an hour, a wide grin etched on her face.

She was excitable even before the party was revealed to the housemates. Locked in the B-block bedroom, she repeatedly sang 'Cookie Love' with Darnell, much to the amusement of Lisa, who commented: "They might do a duet."

Kat also told her roommates how excited she was about the luxury budget and screamed "Cookie Power! Tomorrow!" at the top of her lungs. However, she reiterated that she was not happy all of the time, saying: "I'm up and down."

Kat's screams continued when the housemates were allowed into the living room, to the annoyance of Mikey, who shouted: "Who was that? Shoot them."

But her excitement reached a pinnacle when the music started, as she danced around exuberantly in bright pink wedge flip flops and a yellow dress.
