These pictures from set show Chloe L standing with Chloe M's best friend Courtney Green as the birthday girl blows candles out on her cake.
Chloe M's big day was 2 October.
All the girls look gorgeous and glam - obviously! - and had big smiles on their face after clocking the cake had been delivered by a rather handsome topless waiter!
Fans were surprised when it emerged Chloe L had grown close to Chloe M and Courtney in Marbella, given Chloe L's history with Megan McKenna, who was a good friend of Chloe M and Courtney until their own fall out earlier this year.
Chloe L and Megan had a MEGA fallout over rumours Megan had slept with Chloe's now-ex boyfriend Jake Hall. Megan has vehemently denied this, but Chloe has never believed her.
Meanwhile, Megan fell out with Chloe M and Courtney after accusing them of being bad friends and not having her back. They denied this and said they'd always supported her.
Chloe M told Reveal this week: "We sat next to her on the plane when we went to Marbs and we just clicked! So we've all just stuck together since then.There's a lot of fake people on TOWIE, so when you find someone that's genuinely nice it's good to stay together."
Courtney added: "Honestly, Chloe's just a really nice girl and she's genuinely lovely. Because of everything that was going on between her and Megan, we didn't really get the chance to know her before. We kind of felt like it was just best to take ourselves out of the situation and not talk to her.
"I call Chlo "mummy" – as she really looks after us! At the airport, she kept reminding us about our passports and she helped me with my bags. She's a great girl and she gives us fashion advice, too."
TOWIE airs Wednesday at 10pm on ITVBe.
