From Marvin and Rochelle to Courteney and Johnny… These are the celebrity couples that look like each other and why that could be a good thing

Think about what attracts you to a partner - is it their personality, their humour, or maybe that they look just like you?

For these celeb couples, it appears they may have chosen their other half based on their own looks.

11

Whether you find it adorable or slightly creepy - some of the strongest couples in showbusiness have very similar appearances.

From eyes to lips to jawlines and right down to the smile, these couples have more in common than just fame.

According to research, having similar features to your partner could determine

So, although some of these celebs may even be mistaken for siblings, it means they are more likely to stick to each other.

Marvin and Rochelle Humes

11

Marvin and Rochelle share a similar long face and wide smile, as well as high cheek bones and eye width.

The pair have been married since 2012, which may explain why they have slowly shared the same characteristics when it comes to smiling for the cameras.

Mark Wright and Michelle Keegan

11

Both with a gleaming white smile good enough for the highstreet of Mark's home town Essex, this couple have been inseparable since 2012 - despite split rumours and ex-partners jumping in the mix.

Although Michelle has been pictured numerously in the past without her wedding ring, the pair claim they are stronger than ever.

It may be true that they could last much longer than previously predicted, as they look more and more alike every time we see them.

Courteney Cox and Johnny McDaid

11

The Friends TV star and her Irish fiance appear loved up whenever they are photographed, and maybe their similar faces are part of their bond.

Johnny, member of the band Snow Patrol, has been house-hunting in Derry with Courteney Cox - who has an undeniably similar jawline to her man.

Tom Brady and Gisele Bündchen

Leann Rimes and Eddie Cibrian

Megan Mckenna and (Muggy) Mike Thalassitis

11

This reality-TV star pair have recently been pictured looking very close on holiday together -so close in fact that they may be morphing into each others features.

Minus the stubble, false eyelashes and hair extensions, and you might just have yourself a set of twins!

Brooklyn Beckham and Chloe Moretz

11

With the same messy brows and dazed teenage look, this young couple already look just as similar to one and other as the older, married couples on the red carpet.

Although the pair previously had a break, their relationship seems back on track as they continue to mirror each others expressions.

Benedict Cumberbatch and Sophie Hunter

Denzel Washington and Pauletta

Justin Timberlake and Jessica Biel

11

Sharing eye colour, teeth alignment, jawlines and smiles appear to be the norm of long-term Hollywood couples.

But don't be too disheartened if you look the complete opposite to your spouse, as research says it could take 25 years of living together before you see similarities in appearance.

Just give it a few more years!
