The son of Prince and Princess Michael of Kent has got engaged to his actress girlfriend, Kensington Palace announced today. Lord Frederick Windsor, 29, will wed Sophie Winkleman, 28, later this year after the royal proposed to his partner on Valentine`s Day. The couple have been dating for two years and have yet to set a date for the wedding. The Eton and Oxford educated Lord Frederick works as a banker for JP Morgan`s private banking division. He has previously appeared in upper crust photoshoots for Burberry and is a contributing editor to Tatler. But it`s as a royal hellraiser that his reputation is cemented. Lord Windsor admitted using cocaine in 1999 and, after his mother expressed disappointment, he said: `It`s very difficult to avoid getting into this sort of thing when you move in these circles.` But it seems he may finally be settling down after proposing to Miss Winkleman, who has starred in a number of television comedy series. She`s best known for playing Big Suze in the Channel 4 comedy Peep Show and also starred in the BBC`s Ruddy Hell! It`s Harry And Paul. The actress, who is half-sister to TV presenter Claudia Winkleman, also played Princess Eleanor in The Palace, a drama about a fictional British royal family. A spokesman for Lord Frederick`s parents said: `It is with very great pleasure that Prince and Princess Michael of Kent and Mr and Mrs Barry Winkleman announce the engagement of Lord Frederick Windsor to Miss Sophie Winkleman.`
