Reality TV siren Khloe Kardashian was a one-woman heatwave on Monday in new images shared to Instagram.

The 38-year-old stunner – who will turn 39 later this month – looked incredible in the tiny gold-and-black two piece that made the most of her very toned figure.

The mother of two wore her long, wavy and highlighted hair down over her bare shoulders as she showed off a deep Malibu tan.

The ex of Tristan Thompson was running up the beach when the sun was out, and at one point she carried a surfboard.

The siren was announcing her latest Good American collaboration, this time with watersports apparel and accessories brand Body Glove. ‘Our favorite collaboration to date, this is going to be iconic!’ wrote the BG brand on the GA comments box.

Body Glove is an American brand of watersports apparel and accessories that was founded in 1953 by twin brothers Bill and Bob Meistrell.

The brothers are often credited with inventing the first practical wetsuit in the early 1950s at the back of their Redondo Beach, California surf shop, Dive N’ Surf.

The Keeping Up With The Kardashians vet wrote on her Instagram caption, ‘Inspired by the @bodyglove archive we’re introducing iconic ‘80s swim silhouettes, re-imagined and re-engineered for your body in a new curve lovin’ size range.

‘Mark your calendars, this collab drops Thursday, June 15th #GoodAmericanxBodyGlove.’

Fans went wild for the look. Comments included, ‘OMG u look so good’ and ‘best collab evaaa.’  ‘They’ve done it again with another insane drop,’ added another fan.

Khloe’s brand seems to be doing better than ever. In April she announced that a brick and mortar Good American store was in the works.

‘Our very first @goodamerican store is opening soon!!’ she wrote.

Khloe added, ‘I’m so excited for everyone to experience GA IRL.

‘Stay tuned for the grand opening of our flagship store at the Westfield Century City Mall.’

Khloe posed in a Good American warehouse, donning a sleek outfit from her successful brand. She donned a long shiny black skirt and skinтιԍнт turtleneck in a series of pH๏τos.

Good American also announced its fifth annual roster of models called the Good Squad earlier this month.

Khloe started Good American in 2016 with Emma Grede with the goal of offering clothing for women, made by women – with all body shapes in mind.

According to the website, she has taken ‘inspiration from her personal experiences and frustrations with fashion’ to create the brand.

The brand’s mission is to ’empower women to celebrate their bodies with confidence.’ Since its launch, Good American has branched out to offer denim, ready-to-wear, swim, shoes, and activewear.
