As The Hoff gets engaged, we look at the celebs who are happy in their age-gap relationships

TOY boy, gold digger, sugar daddy, cougar... There is a plethora of terms to demean age-gap relationships.

Here we look at the celebrity relationships that prove age is nothing but a number when it comes to love.

And who better to kick off the list than the newly-engaged and totally loved-up David Hasselhoff...

David Hasselhoff and Hayley Roberts

David Hasselhoff, 63, popped the question this week to 36-year old girlfriend Hayley Roberts.

With 27-years between them, will this be third time lucky for the Hoff?

Sam-Taylor Johnson and Aaron Johnson

You probably remember Aaron as teen heartthrob Robbie in the film, Angus, Thongs and Perfect Snogging, but he is all grown up now at 25.

He met Sam, 42, on the set of Nowhere Boy when he was just 19-years old and she was his director!

They married three years ago and now have two children together, as well as Sam’s two daughters from her previous marriage.

Rosie Huntington-Whiteley and Jason Statham

He’s from an ex-mining community, she descends from royals.

This unlikely Brit couple have been dating for five years and are newly engaged.

After meeting at Coachella Festival in 2010, model turned actress Rosie, 29, and Jason, 48, hit it off straight away.

They went on a break in 2013 but now this pair, with 20-years difference between them, seem pretty smitten together.

Blake Lively and Ryan Reynolds

Despite their 11-year age gap, this gorgeous power couple are the ultimate relationship goal.

After a year of Blake dating the likes of Gossip girl co-star Penn Badgley and Leonardo DiCaprio, and following Ryan’s divorce from actress Scarlett Johanson, the two began dating in 2011 after meeting on the set of Green Lantern.

Blake, 28, and Ryan, 39, are now married and have a one-year-old daughter and are expecting their second!

Mary Kate Olsen and Olivier Sarkozy

One half of the Olsen twins, Mary-Kate, 29, and banker, Olivier, 46, tied the knot in November last year after dating since 2012.

The child star and the brother of the former French president, Nicholas Sarkozy, held a private ceremony in New York, only inviting their closest friends and family.

Sharing a 17-year age gap, the pair have always ignored negative views of their relationship.

Mary-Kate reportedly has a really good relationship with Nicholas’ children and his ex-wife too!

Kate Hudson and Nick Jonas

The on-and-off couple, Kate, 37, and Nick, 23, share an age gap of 14-years and it’s proving difficult to keep-up with their ‘are they aren’t they?’ romance.

Despite claims they are just friends, rumors of romance between the two have been circling since September last year, after they were spotted together in Florida.

The two met up at the recent Met Gala but nothing is reported to have happened.

Johnny Depp and Amber Heard

After breaking up with long-term partner and mother to his children Vanessa Paradis in 2012, Johnny, 52, got together with Amber, 30.

They had met on the set of Rum Diary in 2010 and the Hollywood actor married Amber last year.

Johnny’s daughter, Lily-Rose Depp can often be seen out and about with her dad and step-mum although this acting duo with a 23-year age gap keep their relationship very private.
