If you’re ride or die reality television fans like us, then you’ll totally understand the utter joy of a reality show crossover. When people from one show pop up in another it’s like worlds colliding but in the very best way.

Whether they’ve taken the permanent leap to another set or they’re just popping in to say hello (or you know, propose or something), nothing gives us more life than seeing their eager little faces….

BUT FIRST CHECK OUT THE MOST HEARTBREAKING REALITY SHOW EXITS EVER:

1. Geordie Shore/TOWIE: Ricky Rayment

Ricky wasn’t subtle about his reasons for appearing on Geordie Shore as he took a break from Essex. He appeared in series 11 to propose to Marnie Simpson in Greece. They split shortly after.

2. Geordie/Love Island: Sam Gowland

Love Island’s Sam was well unlucky in love when he fell for Olivia Attwood and Montana Brown so it was twice as nice to see him appear on our Geordie Shore screen in series 16 as a regular family member who quickly fell for Chloe Ferry. Cuuuute.

3. TOWIE/Ex On The Beach: Dean Ralph and Jordan Wright

These two first appeared together on Ex On The Beach series seven and quickly had some major beef with the girls on the show. But cut to the following year and they’re stirring up more drama on The Only Way Is Essex by flirting with some of the taken Essex gals. Classic.

4. Vanderpump Rules/The Real Housewives of Beverly Hills: Scheana Marie

After Vanderpump Rules first aired we were introduced (officially) to Scheana who was known for having an affair with RHOBH’s Brandi Glanville’s ex-husband while the two were still married. Scheana’s boss Lisa Vanderpump asked the Sur girls from Vanderpump Rules to work at her event for her fellow housewives and the two were forced to come face to face. AWKWARD.

5. TOWIE/Ex On The Beach: Megan McKenna

She made a massive name for herself on Ex On The Beach as having quite the temper but Megan left the beach for the streets of Essex when she started dating Pete Wicks. She waved goodbye after the pair split to work on her music career.

6. The Real Housewives of Beverly Hills/The Real Housewives of New York: Bethenny Frankel

Although they all exist in the same hayu universe, we rarely catch a glimpse of the housewives of different cities together. So when New York’s Bethenny popped up during the Beverly Hills ladies’ trip to The Hamptons, our lives were actually made. Until she started insulting Erika Jayne, then we were torn.

7. The Hills/Keeping Up With The Kardashians: Brody Jenner

During his heyday on The Hills, Brody was every girl's dream – that face though. So when he popped up on KUWTK to look after a younger Kendall and Kylie Jenner we put the two and two together - step-siblings. As if that family needed to be more famous.

8. Ex on the Beach/The Charlotte Show: Josh Ritchie

We’d all seen Charlotte Crosby and Josh canoodling on Instagram so it was inevitable that the EOTB star would end up being on her own show. But it didn’t make it any less exciting. Especially when she Googled his actual EOTB appearance and was livid about it.

9. Vanderpump Rules/Summer House: The whole cast

It was the official crossover that we were tricked into. Half way through an episode of Vanderpump Rules, the girls crossed America to hang with their friends in The Hamptons and suddenly we were sucked into Summer House. Like we needed another show to be obsessed with. Thanks world.

Now treat yourself to the reality show couples who were more than happy to bone on TV...
