Hugh Grant has fumed about what he called a "creepy" and "intrusive" encounter at London's Heathrow Airport

In his post, Hugh explained while traveling with his wife, Anna Eberstein, 46, and their kids, the immigration officer's questioning of his family left much to be desired.

He said online: "Just came through Heathrow with wife and children.

"We all have the same last name (Grant) on our passports.

"Immigration officer engages my children in chit chat then whispers to them 'Are these your Mum and Dad?' Intrusive, insulting and creepy."

Hugh, who shares daughter Tabitha Xiao, 13, and son Felix Chang, 11, with actress Tinglan Hong, also has three children with Anna - son John Mungo, 12, and daughters Lulu Danger, nine, and six-year-old Blue. A spokesperson for Heathrow Airport confirmed the immigration officers involved are part of the U.K. Home Office's Border Force, not employees of the airport itself.

A Border Force article on the U.K. government's website notes if a child is traveling with someone who may not appear to be their parent - such as in the case of different last names - officials may ask questions to clarify the relationship.

The government guidance emphasises these inquiries are conducted swiftly and with sensitivity toward both the child and the accompanying adult.

Hugh rose to fame in the 1990s with his breakout role in 'Four Weddings and a Funeral', which earned him a Golden Globe.

Known for his charm and comic timing, he became a staple of British romantic comedies, starring in hits such as 'Notting Hill', 'Bridget Jones's Diary' and 'Love Actually'.

Beyond romcoms, he has earned critical acclaim for dramatic roles in films such as 'Florence Foster Jenkins' and the miniseries 'A Very English Scandal'.

More recently, he has appeared in 'The Undoing' and 'Wonka'.
