Una Healy sets pulses racing in a plunging orange bikini in Costa Rica trends now

Una Healy, 41, made her 662,000 Instagram followers green with envy on Friday as she shared a reel of her holiday antics in Costa Rica.

The former Saturdays singer stunned in a PrettyLittleThing orange brassière bikini set, which she also posted as a stand alone image on her page. 

She paired the swimwear with semi-transparent high-waisted flare trousers, sporting a 70s inspired brown, white, and black zig-zag pattern.

She wore a smoky eye-shadow in the mirror selfie and a dark pink lipstick. 

She added an edgy vibe to the outfit with dagger-pointed pendant earrings and slicked back hair. 

The Absolute Country radio presenter also flaunted her washboard abs and sun-kissed skin in a black bikini as she posed for the shot on a boat trip out in an emerald sea. 

The Up songstress had clearly joined a quick dip in the water, as her wet brunette tresses formed sea-formed curls.

She wore transparent framed Rayban sunglasses to protect her eyes from the glorious sunshine, and her white-painted nails accentuated the bronzed tone of her skin. 

 Una didn't skimp out when it came to packing swimwear, as she later sported a velvet triangle cupped halter neck bikini in a selfie taken indoors.

She emphasised her beach-babe look by keeping her jewellery and make-up minimal, with just a touch and eyeliner and mascara, and letting her wet-locks frame her oval face. 

As well as showing-off her own beauty, the former popstar was sure to capture her stunning holiday destination in the video, caption 'Pura Vida' or 'pure life' in Spanish. 

 Set to Miley Cyrus' new smash hit Flowers, her fans were treated to montage of oceanic sunsets, beach days, boat trips, as well as bikini shots of the Irish stunner. 

Despite the break, the singer didn't give her vocal cords a rest as she enjoyed a singsong with a friend on the beach.
