Megan Fox claimed she was masquerading as a man at this Sunday's Golden Globes.

The Transformers actress showed up at the ceremony looking stunning in a floor sweeping, golden dress and slicked-back hair - only to joke that she was a doppleganger for Alan Alda. 

Megan told E!, "I'm pretty sure I'm a doppleganger for Alan Alda.

"I'm a tranny (laughs)...I'm a man."

It seems even 'Sexiest Woman Alive' Megan Fox has her insecurities, as she confessed how intimidated she felt being surrounded by so many beautiful women.

She said, "I'm so painfully insecure, I'm on the verge of vomiting right now, I'm so horrified that I'm here right now."

So who did she want to trade places with? Selma Hayek seemed to catch Megan's attention with her very own golden globes.

She added, "I really want her boobs. Those are the most amazing boobs. Perfect."
