Mark, 24, had turned up for the first night of filming for the show's upcoming third series, but
despite the abundance of his glamorous co-stars he was focused on his canine pal.
And Lauren, 25, made sure she looked her best when she bumped into her ex.
She flaunted her curves in a low-cut sparkly frock and beamed for snappers, showing she wasn't
affected by seeing him again.
On last night's special TOWIE catch-up episode, Reem All About It, the pair discussed their break-up
and Mark insisted they would never get back together, saying "this time it has to be".
He told viewers: "Lauren knew something was up. I don't think she was happy either. It was kind of
a mutual thing - we weren't getting on.

"The icing on the cake was that I heard rumours she was with a guy in a club, not acting like a
fiancée.
"I love her so much and I know I always will. I'm scared for the thought of her to be with someone
else, but I know I've just got to do it."
But Lauren still seemed angry about the breakdown of their relationship and insisted she hadn't
done the dirty on Mark. She told fans: "I lost respect for him. I didn't really trust him. You've
treated me like c**p again and we're engaged.
"I've not done nothing wrong. You're not loyal to me. I've stood by you numerous times and you
threw it back at me."
And the exes both posted emotional messages online in response to the episode.

Lauren tweeted: "Thanks for all my tweets tonight I have been through a very hard time n trying
be strong feel like I'm the only one that's real everyone playing a game and all out for there self
but people like that u can see through in the end!"
And Mark wrote: "Not gona lie but just watched towie catch up show #reemallaboutitand I shed a
tear and feel very emotional. Will never 4get the good timesx"
He also said it had been "amazing" to see Wrighty, who lives with Lauren, at the bash.
But last night's party wasn't all about Mark and Lauren. The cast turned out for a joint celebration
of his sister Jessica and his mum Carol's birthdays.

The pair, who both opted for long asymmetric white dresses, larked around with their pal as they
posed outside the club.
Glamorous sisters Sam and Billie Faiers showed off their assets in revealing frocks, while
James 'Arg' Argent and Lydia Bright looked loved-up as the only lasting TOWIE couple.
Lauren Pope, who arrived with pal Lauren Goodger and her sister Nicola, flaunted her trim pins in
a short monochrome dress.
And Gemma Collins slipped into a little black dress, showing the result of her recent weight loss
after shedding nearly four stone.
But her new look wasn't quite complete – as she still had a black towel wrapped around her hair.
The Only Way Is Essex returns on Sunday, September 25 on ITV2 at 10.15pm.
