Jimmy Kimmel recently shared details about an unforgettable night at Paul McCartney's star-studded party during an interview with Howard Stern. The event was attended by big names like Taylor Swift, Bruce Springsteen, and Meryl Streep. Swift even took on the role of DJ for a bit using her iPhone, much to Kimmel's amusement. The gathering had around 100 guests, including Kimmel's wife, Molly McNearney, who danced with Jennifer Aniston and Courteney Cox in the kitchen. Kimmel was too nervous to speak with Mick Jagger but had a memorable chat with Springsteen. Butler, also in attendance, was star-struck by Streep and found himself awkwardly meeting her while eating vegan pizza. The night was filled with celebrity encounters and surreal moments, leaving everyone in awe, including Kimmel and Butler who dubbed it as one of the craziest parties they've ever experienced.
