<p>&quot;It&#39;s amazing to really, truly celebrate -- and have my friends around while doing it,&quot; said &quot;The Help&quot; supporting actress nominee Jessica Chastain (in Vivienne Westwood) of the event, which was co-sponsored by Moroccanoil, Audi and Grey Goose.</p>   |   Kevin Mazur/WireImage/Getty Images
The Oscar-nominee announced via her Facebook page that she couldn't fit the Marvel sequel into her schedule.

For Jessica Chastain to appear in the next Marvel film, she would need a supersonic flight suit that could jet her around the world in record speed. Unfortunately, those only exist in comic books -- and via special effects, movies based on comics -- so it turns out that Chastain will not be appearing in Iron Man 3.

THR has confirmed that the Oscar-nominee, who appeared in six films in 2011 alone, was offered the role of a scientist in the third go round of Marvel's most successful single hero film franchise, but has officially passed on the part.

In a note posted to her Facebook wall, she wrote, "Sorry to say that Iron Man 3 isn't going to work out. My schedule is jammed packed and I can't fit anything else in. The press announced my possible attachment far too soon. I know many of you wanted me to be involved, and I'm so sorry to disappoint you. Hopefully there'll be another Marvel film in my future. Shane Black and everyone on the IM3 team are really wonderful. I'm very excited to see the film when it comes out. xx"

Black will helm the Iron Man series for the first time, after Jon Favreau directed the first two. Robert Downey Jr. returns as the titular hero, Gwyneth Paltrow will reprise her role as his assistant and girlfriend Pepper Potts, Don Cheadle will again play Lt. Col. Rhodes. Newcomers Ben Kingsley and Guy Pearce also join the cast as well.
