Tom Cruise

While Katie celebrated her 30th birthday with hundreds of strangers, Tom Cruise hit Hyde for the after-party of his Valkyrie premiere with Connor and Bella!

Tom generously stopped outside of the club to sign autographs with fans, but was he as generous with his beloved for her birthday?

Apparently Tom, "heartsick" over the fact he couldn't be by Katie's side, sent over a ginormous cake, big enough to feed the entire cast, crew and audience of Katie's show.

Ya think that was enough of a "special surprise"?
