Catherine Zeta-Jones posts nude selfie for husband Michael Douglas’ 80th birthday

“After 25 years I am running out of gift ideas.”

There is exactly a 25-year age gap between the pair who share the same birthday and 55-year-old Zeta-Jones shared a snap on Instagram to celebrate their birthday, posing nude in a bathroom with nothing but black heels on.

She said: “In my birthday suit! After over 25 years of sharing my birthday day with my husband, I am running out of gift ideas!

“This is gift option two, golf balls being option one… of course.”

Meanwhile, Douglas posted a black and white picture on his own Instagram of his wife and called her his ‘birthday sister’.

Several celebrities rushed to comment on the posts and send best wishes to the pair.

Alec Baldwin wrote: “The photo. No time for golf.” While Piers Morgan sent a series of laughing emojis before wishing them a happy birthday.

The Zorro star posted another, less racy picture from earlier in their relationship where Douglas can be seen planting a kiss on his then-girlfriend’s cheek.

The caption read: “Happy Birthday to Michael and to me!! This was us on our birthday 25 years ago! I love you with all my heart, our friend snapped us in New York!!”

In another post Zeta-Jones was joined by Bono as they duetted on a rendition of Happy Birthday while she held a cupcake with a candle.

Douglas who starred in ‘Basic Instinct’ alongside Sharon Stone commented: “What a lovely gift! Thank you all for your kind birthday wishes and messages! We love you all!”

While Zeta-Jones, who he has been married to for 23 years replied: “Michael let’s do it all again in 364 days!! Love you.”

The pair met in 1998 at the Deauville Film Festival and embarked on a whirlwind romance before tying the knot a year later.

Together they have a son named Dylan and a daughter Carys Zeta who was born in 2003.
