The beautiful couple jetted to Dubai with their baby daughter Alaia-Mai ahead of Valentine's Day, and so far seem to be having a fantastic time.
Yesterday, the pair cosied up and flashed matching smiles for a pair of sweet selfies uploaded to Instagram that had fans gushing about how they are the "perfect couple".
In the photos Marvin can be seen wearing a very dapper suit, while Rochelle looks absolutely incredible in a white dress with black detailing.
The following day it was no different as they stepped out again looking picture perfect. This time Rochelle stunned in a figure-hugging lime green pencil dress with embellishment details on the shoulders and waist.
Love her look? The good news is you can snap up her exact dress, Cassia – Lime Green Pencil Dress, from Forever Unique. The less good news is it's rather pricy at £300.
This is Rochelle and Marvin's second sunshine holiday of the year following a New Year's family break to the Maldives, but perhaps they're just getting their holiday time in early as it's shaping up to be a big year for the couple.
Former JLS star Marvin is the new co-presenter for The Voice UK, so his weekends will be pretty busy once the live shows start. He also has radio shows on Capital FM and DJs at various venues around the UK and further afield, including Dubai.
Rochelle, meanwhile, and The Saturdays will release their new single, 'Not Giving Up' on 7 April. It's the second track to be taken from their Living For The Weekend album. The group will then hit the road in June for dates in the UK.
Announcing the single this week, her bandmate Frankie Sandford said: "We're so excited. We listened to all you fans and know you all love it so it was a bit of a no-brainer for us. We all love it and thought, 'We have to release it'. We've just finished the video for it. I'm so excited. It's a little different from what we've done before. It will be wicked."
Rochelle and Marvin will also celebrate their daughter Alaia-Mai's first birthday on 20 May and their second wedding anniversary in July.
