To begin, no, Tom Cruise getting spanked by cross dressers didn’t take place in his Imaginatorium. It happened in real life so by Tom’s estimation it was ten thousand times better.
All the stars “got paddled on their rears” by the club’s cross-dressing hostess. Matt got an extra spanking because he was the birthday boy which is nice. Getting more of something is always a good.
No other details on how Tom’s spanking went but I imagine it was great because he didn’t even have to buy him dinner first.
