Mario was joined by Joey Essex, Tom Pearce and James 'Diags' Bennewith on Saturday night (14 September), but no one was more pleased to be reunited with Mario than Charlie SIms.
The lads partied in Club 195 in Epping, Essex and we're sure best pals Mario and Charlie had plenty of catching up to do.
Posting a photo to Twitter, the two friends were seen embracing each other with hugs as they partied away.
Charlie, who has struck up quite a close bond with Mario in recent months, tweeted: "Glad to have my bestie back @Mario_Falcone #SeriousBromance."
Having had the whole of Essex behind him, Mario reached the final of CBB and was voted out of the house in fifth place on Friday night.
The Italian tailor took to Twitter to thank his fans. He said: "So lovely to meet so many amazing people last night... Thank you all for your support.. Love you all! I am truly blessed x."
Now back to reality, Mario has been adjusting to normal life but it seems the thing he missed the most was home-cooked food!
He tweeted last night: "Aaahh so good to be home! Roast!"
