Amal Clooney's mother steals the show at 'Catch 22' London premiere: Photos!

The London premiere of Hulu's "Catch 22" was a family affair for George Clooney!

The actor, who stars in the new series with Kyle Chandler and Christopher Abbott, stepped out on Wednesday night alongside wife, Amal, and her mother, Baria Alamuddin, who totally stole the show.

While the human rights lawyer stunned as usual in a strapless tea-length dress with a silver, sequined bodice and layered detailing on the skirt, her mother looked elegant in her rare red carpet outing in a three-piece seafoam look that she paired with an eye-catching silver-and-emerald statement necklace.

For his part, George looked dapper as ever in an all-black suit over a black button-down that he wore slightly unbuttoned and without a tie.

This is the third "Catch 22" premiere event that George and Amal have attended together: They had previously stepped out for the Rome and Hollywood premieres in the last week.
