Zara McDermott displays her impressive physique in a Barbie pink ʙικιɴι as she tops up her tan poolside in Marbella

They’re holidaying in Spain to celebrate his 30th birthday.

On Thursday, Zara McDermott, 25, displayed her impressive physique in a Barbie pink ʙικιɴι as she topped up her tan poolside in Marbella with beau Sam Thompson.

The former Love Islander looked sensational in the skimpy two-piece swimwear set while relaxing in the sunshine.

Meanwhile, Sam perfectly coordinated with his girlfriend as he sunbathed shirtless in a pair of purple and pink sea world print swim shorts.

On Made In Chelsea star Sam’s birthday on Tuesday, Zara shared a montage of videos and pictures throughout their relationship alongside a heartfelt tribute to her beau.

She penned: ‘HAPPY 30th BIRTHDAY❤️ I cannot believe you’re thirty! Our relationship is non stop laughter, you annoying me (which I wouldn’t have any other way), but it’s also supporting each other in every way and being each others biggest champion.

‘I am so grateful for you every day. Your infectious energy is the most wonderful thing to be around. You have this amazing gift where you can light up any room you walk into.

‘No matter how bad of a day someone is having, you can always make them smile, laugh and forget about their worries. You are so kind to every single person you meet, which is so rare nowadays.

‘I hope you enjoy this video of some of our funniest, belly laugh moments. I can’t wait to keep laughing with you until we are old and grey!!!’
