Kim Kardashian posts sizzling snap of Kris Jenner from the '80s in revealing pink bathing suit

She's been called the favorite daughter on Keeping Up With The Kardashians, and now we can see why.

On Sunday - Mother's Day in the US - Kim gushed about her 58-year-old mother Kris Jenner while posting a very flattering photo of the matriarch from the late eighties on Instagram.

'I have the hottest mom! LOL,' the 33-year-old reality star captioned the image. 'This was her after 4 kids!!!!! My hero!!!'

She was a 10 in the '80s: Kim Kardashian shared this photo of her mother Kris Jenner on Instagram Sunday, which was Mother's Day in the US

She looks good too: Kim in a white dress for her wedding shower in Beverly Hills on Saturday

The fiancée of Kanye West, who had baby North with the rapper 11 months ago, added: 'I am me because of you!!! Thank you for showing me what compassion, strength and family means!!! I love you.'

In the shot Jenner looked very in shape and wearing a fresh tan.

Her hot pink one-piece bathing suit is cut high on the hip and there is illegible print on the chest area.

A white fedora with a black band on it rests on her head, covering most of her short crop hair cut. Dark aviator sunglasses cover her face.

The photo must have been taken in the morning because the E! producer is seen holding a cup of coffee or tea.

With one bare foot on her knee and her right arm pushed back, the looker - who was married to attorney Robert Kardashian at the time - seemed to be striking a model pose. She is standing on the patio of a home next to a lounge chair.

The photo looks to be taken in a tropical location such as Hawaii or Mexico.

Because there are tall buildings in the background, the area appears to be well populated. Mountain ranges behind her are high and the skies have light clouds in them.

At the time, Jenner had four children already: Kourtney (now 35-years-old) Kim (now 33-years-old), Khloe (now 29-years-old) and Rob (now 27-years-old).
