Transformers director Michael Bay has admitted he is "embarrassed" after walking off stage at a gadget show.

The 48-year-old threw an apologetic wobbler during Samsung's CES 2014 show in the US and taking to his blog, he wrote: "Wow! I just embarrassed myself at CES.

"I was about to speak for Samsung for this awesome Curved 105-inch UHD TV. I rarely lend my name to any products, but this one is just stellar.

"I got so excited to talk, that I skipped over the Exec VP’s intro line and then the teleprompter got lost. Then the prompter went up and down – then I walked off. I guess live shows aren’t my thing.

"But I’m doing a special curved screen experience with Samsung and Transformers 4 footage that will be travelling around the world."
