The singer, who is pregnant with twins, WILL headline the festival in 2018 -- so at least the Beyhivé has that!
In a statement to The Associated Press on Thursday, Bey's Parkwood Entertainment and festival producer Goldenvoice said:
Jamie Lee Cheerleader was seen at the 17th Annual Dream Halloween event, which was held at The Barker Lounge.
The event seeks to benefit the Children Affected by Aids Foundation.
We think Jamie looked great, and we're happy to see her supporting such an important cause!
What do U think of Jamie's costume?
