Luisa Zissman displays her washboard abs in a pink bandeau as she poses for stunning selfie

Luisa Zissman exposed her washboard abs when she took to Instagram on Easter Monday.

The former Apprentice contestant, 35, showed off the fruits of her labor as she posed in a pink bandeau for a stunning selfie.

She ran a hand through her dark blonde locks and framed her face in oversized black sunglasses.

In her caption, the Celebrity Big Brother star wrote, “Happy Monday. How do you spend yours? ❤️.’

Luisa donned a yellow bikini as she visited a farmyard on Saturday during her sun-soaked getaway in Thailand.

She looked sensational in the skimpy two-piece as she posed for a slew of cute snaps with a herd of pigs.

The swimsuit featured a bandeau top and high-cut bottoms and showed off her slim figure perfectly.

Luisa shielded her eyes behind oversized sunglasses and wore her caramel locks – ironically – in pigtails as she got dirty in the mud.

Writing: “There’s a reason the phrase ‘happy as a pig in s***’ exists.”

“Today I experienced the expression in real life and I can confirm that when I rolled around with these guys I really was as happy as a pig in s***.”

Last year, Luisa revealed she has African ancestry after finding old photos of her great-grandfather and other relatives.

She also shared how she believes she is related to former South African president Nelson Mandela.

On her recent podcast episode with co-host Anna Williamson, the reality TV star explained how people “wouldn’t believe her” if they didn’t see pictures to prove it — so she later shared photos of her late relative on Instagram.

Speaking on the subject of family traditions, Luisa brings up her “affinity” with Nelson Mandela on the LuAnna podcast.

“Did we talk about my black grandpa on the pod? We have to post the photos or people won’t believe me,” she told co-host Anna Williamson.

“We had family over and the old photos came out – I think I realized my affinity for Nelson. I do believe I am related to Nelson Mandela.

“Because when we saw my great-grandfather’s picture, it was black.

‘We don’t really know where in Africa he came from, we just know that he was African. He may have been West African, but we don’t know. How do I find out?

“I would like to think that I am related to Nelson Mandela.

She added that the man she is referring to in the photo is the father of her grandmother, whose mother was Italian.

Luisa adds: ‘She even looks black, doesn’t she?’

“Now his eldest son is the only one alive of the four children,” Luisa explained.

‘My Nonna [grandma] passed away, my mother’s two uncles passed away, and there’s only one left – and he’s old and starting to get alzheimer’s.

“There was also a suspicion that my great-grandfather was a spy… now that my great-uncle Hector is on the decline, he keeps talking about the fact that he would have to go through the tunnels with packages and meet soldiers in Germany.”

She later took to Instagram to show her 625,000 followers exactly what she was referring to in the episode.

Luisa wrote in a caption to two photos that showed her grandpa and other deceased relatives, “Hey guys, if you’re listening to LuAnna: The Podcast, I know I promised pictures of my great-grandfather.

“Please, the little girl in the photos is my Nonna (Italian for grandma), so my mother’s mother. The boys are her brothers.

“The eldest boy (Uncle Hector) is the only surviving sibling alive (out of 4) ❤️ told you I was African and you didn’t believe me.”

Luisa’s revelations come not long after she was criticized by Ulrika Jonsson for labeling NHS workers planning to strike as ‘cruel’ and saying staff should never have entered the profession if they were worried about salaries.

She denounced National Health Service staff, calling them “irresponsible,” “cruel,” and “bounced.”

Write in her column for The sunUlrika said Luisa’s comments were “heartless” when she praised nurses for the work they do.

She wrote, “Zissman’s remarks about nurses are not only extremely heartless, but a display of impeccable ignorance.

“Sometimes you have to wonder if some people aren’t completely devoid of intelligence and empathy.”

Ulrika said that being a nurse requires his “dedication” and no one who chooses it as a career is doing it for the money.

Although she doesn’t like the planned strike, Ulrika says she likes it even less that “accountants at the top” have six-figure salaries, while those at the bottom “have their backs against the wall.”

Ulrika added, “She doesn’t care what I or anyone else thinks of her comments – that’s why, thank God, there will never be a Nurse Zissman.”
