Gordon Ramsay delighted fans when he revealed that he and his wife Tana had welcomed their sixth child after keeping their pregnancy secret for nine months.

The celebrity chef made a surprise announcement on 11 November, welcoming his newborn son Jesse James Ramsay and dubbing him "one more bundle of love to the Ramsay brigade," in a heartfelt Instagram post dedicated to his wife.

On Monday, Gordon and Tana's daughter Holly shared two unseen photographs of the newest addition to the Ramsay family - and fans can't get over how much the three-week-old baby looks like his father.

Sharing a gallery of her "November highlights," Holly, 23, looked to be in her element as she took on the role of big sister in a sweet family photo.

The star cosied up to her little brother Oscar, three, and cradled her newborn brother, Jesse, who was wrapped up in a white babygrow adorned with London motifs.

It's clear to see the Ramsay genes are strong, with Jesse already adopting his father's signature 'grumpy' face, which gained Gordon notoriety as a fearsome and talented chef on cooking programmes like Hell's Kitchen.

It's not the first time Gordon's children have been likened to him. Three-year-old Oscar has been declared the "spitting image" of his dad, 57, as the Ramsays continue to share adorable photographs of him growing up.
