Photos of the odd couple meeting up behind the scenes have been circulating online this week, beg February 10, but the Mexican actress admits they don't tell the whole story.
"In these pictures it might look like @Eminem and I are best friends, but what really happened is as he was walking offstage and I was getting ready to walk onstage, I was so shocked to see him that I spilled water all over him," she tweeted on Wednesday, February 12.
"If you examine our faces, I look mortified and he looks terrified of me. As I was trying to wipe it off I impulsively hugged him and I said 'Nice to meet you Eminem - I'm a HUGE fan!' because I AM! But I was so disappointed that I made such a fool of myself in front of him..."
But she was stoked when she read the rapper's account of his Oscars night out in Rolling Stone and he revealed a highlight was hugging Salma.
Sharing a link to the piece, she added, "and then I read this in @RollingStone. @Eminem you're the greatest!!!"
Eminem made his debut at the Academy Awards on Sunday, when he performed his 2003 Best Song Oscar winner "Lose Yourself" from "8 Mile".
