Meeting your favourite celebrity or a person you idolise can be a transcendental experience, but when you yourself are famous already, it adds a whole new exciting layer to the interaction!
I'm kind of obsessed with celebrities meeting other celebrities they adore, so here are 17 of the best encounters I could think of to warm your heart today!
1. In 2008, a 19-year-old Alexandra Burke won The X Factor and sang with Queen Bey in the final, which was evidently quite overwhelming for the singer.
2. While filling in for Jimmy Kimmel, Kristen Bell chose to surprise Star Wars superfan Adam Scott with the one and only Mark Hamill! Watch out for his trembling fingers... 😭😭.
3. Oscar-winner Emma Stone has talked about her love of The Spice Girls on many occasions, but she almost went to pieces when she was shown a video message from Mel B in an interview with 2DayFMSydney.
Here's that savage Graham Norton clip by the way:
4. In a skit for Saturday Night Live from 2006, Alec Baldwin was told to expect Paul Simon as a cameo, but Paul McCartney walked in instead, leaving Alec ~literally~ mouth wide open in shock.
5. I love this moment between Nicki and Lauryn, in which the queen of rap meets her idol and literally worships her from the floor.
6. When they both appeared on The Late Late Show With James Corden, Seb could NOT contain his excitement at meeting Sharon Stone in person, even sticking it on her in a BIG way!
7. Having impersonated her on "Snatch Game" during season nine, we were all gassed for Drag Race alumna Shea Coulée when she got to meet Naomi Campbell.
8. When he first appeared on The Graham Norton Show, Olly Alexander was visibly over-excited to meet his idol Rihanna, who was also on the show promoting Ocean's Eight.
9. Hollywood's biggest fangirl, Jennifer Lawrence, once crept up on Jeff Bridges during an interview to tell him that she loved him.
10. In one of the most bizarre crossovers on this list, movie legend Diane Keaton spoke about her love of Justin Bieber, only to be surprised by him on The Ellen DeGeneres Show.
11. For a long time, Ariana has been open about her love of Jim Carrey. When she met him for the first time in 2014, the singer teared up and then posted a short clip on her Instagram saying "me meeting Jim Carrey 😭😭😭😭😭😭".
12. Reportedly, Harry Styles is good friends with the legend that is Stevie Nicks. At his Fine Line album launch concert in 2019, he invited Stevie to sing "Landslide" on stage with him, commenting that she'd been a "light" for him.
13. Self-confessed Friends stan, Charlie Puth, stopped by The Ellen DeGeneres Show where they discussed his love of the show, the possibility of a reboot, and his adoration of Jen. Cue a blindsided Charlie as Jen walks out!
14. Perhaps the most wholesome encounter on this list is between a sixteen-year-old Brandy and music legend Whitney Houston. Brandy almost immediately bursts into tears!
15. Incredibly, movie icon Julia Roberts once had a total meltdown because Gwen Stefani was behind her on a red carpet.
16. When participating in "Carpool Karaoke" with James Corden, Sam Smith revealed that they were a big fan of Fifth Harmony. Cue James pulling over and Fifth Harmony getting into the back seat!
17. Lastly, I LIIIIIIIVE for this meeting between Oprah and her biggest fan, Tiffany Haddish!
18. Bonus: Here's a clip of the opposite! Kesha crashes Jerry Seinfeld's interview, and proves that sometimes you shouldn't meet your heroes.
