'Skyscraper' singer Sam took daughter Brooke along for the theatre show at the London Palladium on Saturday.
Former Pussycat Doll Nicole plays Grizabella in the Andrew Lloyd Webber musical, and it seems her performance is going down a storm!
After the show, Sam tweeted: "@CatsMusical wow what a show xx so good to see the wonderful @NicoleScherzy. Stunning performance."
Sam stormed to victory on The X Factor in 2013, where Nicole was a judge at the time.
Nicole also features on Sam's debut album, The Power Of Love for a rendition of 'And I Am Telling You', which is the same song the pair performed during the show's final two years ago.
'Your Love' singer Nicole has had a string of famous faces supporting her since making her West End debut in the play in early December.
Last week, Nicole was supported by TV presenter Laura Whitmore and Hollywood star Tom Cruise! Of course, Nicole's Formula One ace boyfriend Lewis Hamilton has also been supporting his girl throughout.
Nicole will be playing the role for a strictly limited 12-week run. She's expected to perform her final shows in mid-February.
