It's officially been 25 years since Friends first premiered.

But thanks to constant re-runs, Netflix, and catchy one-liners, our love for the beloved sitcom is still going strong. Which is why we were particularly excited when we saw the latest addition to Penneys' Friends range. The retailer have revealed matching pyjamas sets celebrating one of the series' best friendships: Rachel Green and Monica Geller. One set features green plaid shorts with a red bow, and a grey t-shirt that says "She's My Monica Geller" in red writing. The other features red plaid shorts with a red bow, and a white t-shirt that says"She's My Rachel Green" in green writing. The pyjama sets were first shared on Primark's official Instagram account, and fans have been going crazy for them ever since. "Happy 25th Birthday to one of our all-time favourite shows! We’ll be celebrating by watching back-to-back episodes and shouting ‘we were on a break!’ at every opportunity," they captioned the photo. These would definitely be perfect for the next Friends binge-watching session with your BFF. If you're looking for more information on Friends' milestone anniversary, you can test your knowledge of the pilot here. Marta Kauffman and David Crane, the co-creators of Friends, have revealed the storylines the they regret the most. There's also a Christmas Friends festival headed to the UK later this year - and could we BE anymore excited?
