They also stood side-by-side in the water briefly, as Vick threw her head back to enjoy the sun with her long hair flowing loose behind her shoulders.
While on the beach, the former Strictly Come Dancing star donned her triangle bikini top and a pair of ripped denim shorts.
At one point, Calvin tenderly leaned over her shoulder to look at a series of selfies she’d snapped of the pair of them together on her phone.
They also lay back together on a few beach towels on the sand and snuggled up.
Taking a little time out of the sun’s glare too, the pair were spotted sitting outside at a restaurant, deep in conversation.
Summer chart-topper Calvin had slipped on a black and yellow floral print shirt, while Vick wore a black and white patterned handkerchief top.
During their chat, Vick held her hand up to Calvin’s face while he gently kissed the inside of her wrist in a sweet and relaxed display of affection.
The pair reportedly dated in secret for five months before making their debut, following Calvin’s split from model girlfriend Aarika Wolf, 27, in March after four years of dating.
A source claimed that Vick and Calvin are ‘smitten with each other’ and already planning their forthcoming nuptials.
‘They could not be happier and are already planning their wedding, which is set to take place in Ibiza, where they grew close during Vick’s secret visits to the White Isle.
‘After keeping their relationship private, they decided to go public at the Chelsea Flower Show on Monday, they want everyone to now know their happy news,’ they told MailOnline.
Neither Vick nor Calvin has spoken out on their relationship or to confirm their engagement.
Vick previously revealed in 2018 that she actually turned down her now partner after he asked her out back when she was 19.
Speaking on her former Capital show, she recalled: ‘He looked how he used to look and I was shallow, I was 19, and I said no and I went off with one of either Scouting for Girls, or The Wombats, I don’t know which.
‘They were there, I thought they were going to be bigger but no, it turns out Calvin Harris was going to turn into an Adonis.’
