Chloe took to Instagram on Sunday (15 March) to send a sweet message about how she was enjoying the celebratory day.
The photo is too cute for words, as it shows baby Ace clutching onto his mummy's hands, with his eyes and mouth wide open.
Commenting on the photo, Chloe said: "First Mother's Day with the most beautiful little boy I could have ever wished for! @jbgill xx."
Meanwhile, JLS star JB also praised his wife. Sharing the same photo on Instagram, he said: "Happy 1st Mother's Day to my beautiful wife @ChloeSGill thank you for all you've already done and will do in Ace's future! Mwah x."
The Jump star JB and his dancer wife Chloe welcomed Ace on 19 September last year.
Speaking about Ace in January, JB said: "We're so blessed," JB says. "He's brilliant, he's such a joy. It's an incredible time in my life."
