Holly Willoughby has celebrated her ninth wedding anniversary by posting a rather cheeky pic on Instagram of herself in some personalised bikini bottoms.

The 35 year old ‘This Morning’ co-presenter, who married her TV producer husband Dan Baldwin in 2007 at Amberley Castle in West Sussex, posted a holiday pic on Wednesday (August 4th) of some black bikini bottoms she was wearing, with her married name ‘Mrs. Baldwin’ written in diamante on them.

“Nine years ago today I became… #love #Hubby #happilyeverafter” she wrote in the caption. Fans joined in with the fun, with one writing “and you never looked back, um - I mean behind…”

Nine years ago today I became... #love #Hubby #happilyeverafter ??????

Speaking to Bella magazine recently, Willoughby recalled her wedding day. “It was one of the best days of my life. One stand-out moment for me was walking into the marquee and seeing everybody that you know and love looking back at you. It was a beautiful summer's day too and just felt like a dream - a magical moment.”

In another interview with The Sun, she said that she and her husband accredit their happy marriage to not underestimating the effect of tiredness on a relationship – particularly when new babies are involved.

"I do believe tiredness has a lot to answer for. Everyone underestimates the effect it has on you as a couple. “Whenever I see people breaking up shortly after they’ve had a baby, sometimes I wonder if they’d just given it a little bit longer or pushed through that tough bit at the beginning… Not that I profess to know everything about other people’s relationships, but I think that people may make decisions at that stage and then wish that they’d just held out or worked through it.”
