The 50-year-old rocker - who was married to Nirvana frontman Kurt Cobain until his suicide in 1994 - couldn't get enough of the 'Kiss You' hitmakers as they hung out together at the Saturday Night Live TV afterparty in New York over the weekend and was keen to take selfies with the group.
The band - made up of Louis Tomlinson, Niall Horan, Liam Payne, Zayn Malik and Harry Styles - are said to have equally enjoyed their encounter with Courtney, with Louis, 22, particularly pleased about meeting "rock royalty".
Following the bash, Courtney shared a photograph of herself with Louis to her 775,000 Twitter followers with the caption, "Good times with some great guys."
Meanwhile, Harry Styles was spotted enjoying himself with 'Bridesmaids' actress Kristen Wiig, 41.
The 20-year-old heartthrob was filmed dancing with the star to the 1987 hit 'Time of My Life' from the musical 'Dirty Dancing' at the event on December 21.
