Ulrika has revealed that David Frost once phoned her, but only to ask for a weather forecast.
The ex-weathergirl admitted to feeling embarrassed after thinking the telephone call was simply for a celebrity-celebrity chat.
Ulrika told the housemates: "I had this phone call through, and the secretary said it was David Frost.
"'I have my summer party this weekend,' he said. 'And I just wondered if you could tell me what the weather is going to be like.'
"I went from there to there," she added. "I knew my place."
