Kathy Hilton has never been apart from her husband for more than two weeks.
The 65-year-old reality star has been married to businessman Richard Hilton, 69, since 1979 and just days after celebrating their 45th wedding anniversary, she has admitted that the "key" to their success is keeping the "right influences" around them.
She told People:"We're best friends. And, I was just saying to someone, getting married so young like that — I was 19 and he was 23 — [the key is] just keeping the right people around you, the right influences and being around other couples who are happy [and] have the same values as you. We have not been away from each other for two weeks in [all our years] of marriage."
The 'Real Housewives of Beverly Hills' star - who has Paris, 43, Nicky, 41, Barron, 35, as well as 30-year-old Conrad with Richard - noted that the pair of them don't go to bed on an argument and always try to "keep a little mystery" in their marriage to keep the spark alive.
“I don't think you go to bed without saying, ‘I love you,’ and giving each other a kiss and never in a fight or anything. If you have had a disagreement, you always make up before you go to sleep and keep a little mystery and always keep it exciting and fun.
For their anniversary celebrations, Kathy and Richard went on a trip to Paris and London, and she revealed that she indulged in the British appetizer of pigs in blankets, which are a festive tradition made up of chipolatas wrapped in bacon, as they flew back from the English capital.
She said: "We did five days in Paris and seven days in London. It was shocking, it was gorgeous. My husband put it on his Instagram. One thing I do love, and it’s always at all my parties all through the years, are pigs in a blanket and I didn’t realize the Brits — that’s part of their Christmas dinner. So I got another pig in a blanket [on the plane]."
