The former Coronation Street actress has grown close to Arg during the past few weeks of filming the new reality show, so it seemed only right to give him a peck on the cheek!
Helen was also joined by one of the show's executives in giving Arg a kiss as they partied the night away in Liverpool nightclub PopWorld.
Sharing a picture of his lucky moment with fans on Twitter, Arg commented: "Ended up in PopWorld Liverpool! Haha wrap party kisses with exec 'n' @helenflanagan #CSS."
During filming, Helen caught Arg stuffing his face with McDonald's after he sneaked off to a producer's office.
Yesterday (14 August), she shared another picture with her Twitter followers after being sent out to get Arg's rather substantial breakfast from bakery chain Greggs.
Helen said: "Arg's breakfast of 3 Greggs rolls x" He then replied, saying: "Now that's what I call MORNING GLORY!!! Lol x"
It has been rumoured that Helen and Arg have fallen for each other romantically while filming the TV series, but whatever the case, it seems they are definitely BFFs!
