On movie marquees, she's Jamie Lee Curtis. On restaurant reservation lists, look for the Baroness Haden-Guest.
The star of "A Fish Called Wanda" and her daughter watched from the visitors' gallery Monday as Curtis' husband, actor and screenwriter Christopher Guest, took his seat in the House of Lords.
Guest, who starred in "This Is Spinal Tap," became the fifth Baron Haden-Guest last year upon his father's death. Monday was his first appearance in the unelected upper chamber of Britain's Parliament, where he swore the formal oath of allegiance to Queen Elizabeth II.
He sat on what are known as the crossbenches, the place for peers who aren't affiliated with a political party.
"We usually watch your Parliament on satellite television in America," Curtis told the Daily Telegraph afterward. "It's quite beautiful and obviously daunting. It's important for us to be here to support my husband."
The London paper reported that the daughter of Tony Curtis and Janet Leigh has told friends she uses her title only to "book a table in a very good British restaurant."
