Adam told us: "I love having a drink in a bar and getting goofy but at this point I have to keep focused."

Which means no drinking or silliness for the star. Aww.

Last night he did his best to put on a brave face although the thought of drinking water the entire night would be enough to make anyone pout!

The American donned dark clothes dressing in black jeans, a black t-shirt and a black blazer — he certainly looked dramatic.

He wore his trademark hair spikey and finished the look off with black nails and chunky metal jewellery.
