The stars stepped out on Wednesday in Los Angeles in support of amfAR's Inspiration Gala. Among the star-studded guest list was Miley Cyrus (and her revealing dress), who dropped $500,000 at the auction - causing Gwyneth Paltrow to take notice of the "Wrecking Ball" singer's financial worth.
"I'm drunk now so this isn't fair," Paltrow joked, "And Miley Cyrus has so much more money than I do!"
Paltrow, who hosted the event, took the stage several times at the AIDS research benefit, but it was how she introduced a surprise performance from her soon-to-be ex-husband, Chris Martin, that had the crowd buzzing.
"This brilliant singer-songwriter has sold 8 million records, has won every single award that there is to be won, especially Father of the Year, which he has won consecutively since 2004," Paltrow said. "I am speaking of Chris Martin and the incredibly talented Jonny Buckland, who together make up one-half of the legendary band Coldplay."

Earlier this week, Chris split from Jennifer Lawrence. The couple began dating back in June -- and several reports claim it was Chris' close relationship with Gwyneth that drove the Hunger Games starlet away.
What do you think of Gwyneth's amfAR antics?! Did her joke about Miley make you laugh? And, are she and Chris the friendliest exes in Hollywood?! Let us know on Twitter by sending @Katie_Krause a tweet using the hashtag #ETnow!
