Keke Palmer Masters the Mechanical Bull at Just Jared's Summer Fiesta!

Keke Palmer braves the bull by riding with one arm in the air at the 2014 Just Jared Summer Fiesta on Saturday (July 12) at Pink Taco in West Hollywood, Calif.

The 20-year-old entertainer had a blast dancing by the DJ booth and enjoying all that the party had to offer. Make sure to check out her brand new talk show Just Keke every weekday at 5/4c on BET. We sure approve of the name!

Amber Rose shielded herself from the hot sun by wearing a pink cap.

“Thx @justjared!!! #aeriereal #SummerFiesta,” Amber posted on Instagram along with a photo from the aerie photo booth. Check it out below!

Guests at the party enjoyed Red Bull to keep up their energy all day long. We’re pretty sure it gave them the courage to ride the mechanical bull!
