Robbie Williams' wife Ayda Field is rushed to hospital with an undisclosed medical problem hours after a night out in Beverly Hills

Ayda Field alerted social media followers to an emergency room on Sunday after she was taken to hospital with a mystery illness.

The wife of former Take That star Robbie Williams imagined herself being treated with an IV as she rested on a hospital bed, with a mounted heart monitor visible on the wall at her back.

Ayda, 44, addressed the incident with Instagram followers and thanked her husband for his support after she fell ill following a night out in Los Angeles.

She captioned her post: 'After a perfect evening, a less than perfect ending. Now back and resting thanks to my amazing husband @robbiewilliams for being by my side.”

The night before, Ayda had enjoyed a night out with Robbie, 49, at popular Beverly Hills restaurant Cipriani, where they were joined by Dame Joan Collins and her husband, Percy Gibson.

Robbie is linked to Dame Joan through the British actress' late goddaughter, Milica Kastner.

Milica, the daughter of American film producer Elliott Kastner and British celebrity interior designer Tessa Kennedy, died of terminal cancer in March 2021 at the age of 49, two years after she was diagnosed with stage 4 colon cancer and stage 4 uterine sarcoma.

Robbie and Milica became close friends after the film producer moved in next door to the Take That star while living in Notting Hill.

In a self-penned piece for Tatler, Milica wrote: 'From that first night in Notting Hill that Robbie and I met, we were inseparable, like brother and sister. I eventually moved to Los Angeles in 2001 and lived there with Robbie for two years.”

Milica also revealed that during her pregnancy with her son Jack, people assumed the baby was Robbie's.

“While I was in LA, I got pregnant by one of my oldest brother's friends, Cary Woods,” she recalls.

'When I went back to London, pregnant with Jack, everyone thought the baby was Robbie's, but we were and have always been just friends.'

Robbie and wife Ayda are parents to daughter Teddy, 11, and sons Charlie, nine, and Beau, three.

The couple has largely kept their children out of the public eye, with Teddy recently making a brief appearance in the singer's Netflix documentary.

Their eldest child was also in the spotlight in 2018 when she was a flower girl at the wedding of Princess Eugenie and Jack Brooksbank.

Ayda previously admitted it was her idea to document the birth of the couple's second child through a series of bizarre social media videos, which went viral online.

The American star spoke about her childbirth experiences during an appearance on Loose Women, when she revealed she encouraged her fun-loving husband to 'wander around' to distract her from the pain.

Son Charlie's birth was caught on camera when the former Take That star posted a series of bizarre videos and photos of himself with his wife in hospital in Los Angeles.

She explained that many people didn't believe she was actually in labor when the videos and photos were shared online, insisting: “I was actually in labor, I have to say poor Rob got a lot of criticism but it was my idea .

“It wasn't our intention, it started when I jokingly put on my heels, put them in the stirrups and he asked to tweet it.”

Robbie shared videos of them dancing together in their hospital room and singing his hits while Ayda was in labor.

'It was 3 o'clock in the morning, a 17-hour labor. It kept me distracted, we came up with all kinds of funny bits,” Ayda told her Loose Women colleagues.

'It's our sense of humor, we're goofy. But I didn't think it would go viral. About an hour after the birth, a lady came over and said, “Oh my god, those videos are so funny!”

'Then a cleaning lady told us she saw us on Spanish TV that morning and another said we were on Good Morning America and I asked, “honey, what happened?”
