The All Saints singer took to Twitter account on Tuesday 28.06.16) to reveal her beloved kitty, named Lady Our Kid, has passed away at the age of 19.

Nicole bought the pet when she was dating Robbie back in 1997 but when they separated in 1999 she kept the kitty and then when she embarked on a romance with Robbie's pop rival Liam, the pussy lived with her and the former Oasis frontman.

The 'One Strike' singer let the former Take That star know the cat had passed in her Twitter post in which, as well as containing a photo of her hugging the moggie, she wrote: "I lost my best friend of 19 years tonight ..ladyrkid..I'm hurting so bad!..@robbiewilliams (sic)"

Robbie, 42, has now posted on his own Twitter account, "Here's to you Lady Ourkid . Bless #RIP," followed by a heart emoji.

Nicole, 41, responded to Robbie's tweet with a simple broken heart emoji.

Liam, 43, posted his own photo tribute to his feline friend on his Twitter account, simply writing "RIP KID".

Nicole retweeted her ex-husband's post, showing that there is no hard feelings between the pair following their divorce in October 2015.

The ex-couple's five-year marriage imploded in August 2013 when Nicole dumped Liam - with whom she has 14-year-old son Gene - after it was revealed he had fathered a child with American journalist Liza Ghorbani.

Robbie is now married to American actress Ayda Field and the couple have two children, daughter Teddy, three, and 20-month-old son Charlton.
