The couple have splashed out on a new property in Los Angeles for weekend breaks and for when they need to work in the city, and daughter Kelly says they are very happy with their purchase.
Kelly said: "It`s the cutest thing how in love my parents still are.
"They`ve just got this little love nest in Los Angeles now for when they come here for work, because they actually live an hour outside the city.
"It`s really sweet and cheaper than getting a hotel every time.
"My dad`s always said, `All I need is a room with a TV and a dog! Why do we need all this stuff?` And he`s really content there."
Kelly - who recently split from fiance Luke Worrall - currently has her friend Chris staying with her and admits her pal is a bad influence on her diet.
She added in her column for Closer magazine: "My brother Jack is directing my dad`s music video this week and loads of people are working on it at his house, so our friend Chris, who lives with Jack, is sleeping on my floor.
"We`ve always said if we lived together we`d be the happiest, fattest people ever because all we do is order food, put on stupid TV and giggle.
"It`s like a sleepover having him around - it`s so much fun. We`ve not been too well behaved with food though, so it`s a good job it`s not permanent."
