Poppy Delevingne's hen night didn't feature 'L' plates or wedding veils, but it did see Harry Styles and his best pal Nick Grimshaw dress up as 90s brother band Hanson for the model's big do.
The pair donned wigs and grunge plaid shirts as they headed off for the retro-themed hen do at the Groucho Club, along with friend Gillian Orr.
Harry tweeted a snap of Sienna Miller at the bash, but she wasn't the only A-lister as the hen night saw the likes of Alexa Chung, Jaime Winstone, Cara Delevingne and Georgia May Jagger celebrate Poppy's last days of freedom.
Harry, who sported an elephant mask, on his way out of the private members' club, has most recently been linked to Daisy Lowe, after the pair both attended Alexa Chung's 30th birthday earlier in November.
But this is just a week after the One Direction star was linked to Kendall Jenner. We don't blame you if you can't keep up either!
