Dancing On Ice judge John Barrowman once caught his mum in bra and suspenders getting ready for hanky-panky with his dad.
The star got a shock when he turned up on their doorstep without warning that he was heading home.
The American actor and singer was studying in Chicago at the time but decided to make the two-hour trip to Illinois see his parents one weekend.
However he was lost for words when he spied mum Marion standing in bra and suspenders with a glass of whisky on a tray ready to surprise husband John when he got back.
The Doctor Who star revealed: “I said to her ‘What are you doing dressed like that?’
“And she said ‘You’ve got to keep it fresh!’”

To get in on the act, game for a laugh Barrow-man pulled up his shirt like a bra and stood behind the door with a whisky and waited for his dad.
When John senior got back, he called out Marion’s name but was greeted by the sight of his son and yelled: “What the f*** are you doing home?”
Barrowman spills the beans in the new series of BBC One’s All Round To Mrs Brown’s on Saturday at 9.15pm.
He and his parents are guests, but when they tell Agnes Brown (Brendan O’Carroll) embarrassing stories about his childhood, he turns the tables.
The star says: “You’ve been telling enough stories about me, so I’m going to tell one about you!”
