'Big Brother': Mark And Christopher Rekindle Their Romance With A Kiss In The 'BB' Bedroom

Sparks flew once again in the ‘Big Brother’ house during Tuesday night’s highlights show, when Mark and Christopher were shown rekindling their romance and sharing a kiss under the covers in the ‘BB’ bedroom.

The pair picked up where they left off - having already had a cheeky snog earlier in the month - after once again growing close when neither of them received a letter from home.

There were tears aplenty as the housemates gathered around the sofas, with half of them receiving letters from home, as decided by Winston.

When Helen was chosen to receive a letter over Mark, he told housemates he was happy to let the mouthy hairdresser hear from her son back home.

However, during a private moment later on, Mark headed to the toilet where he was seen crying on his own, with Christopher chasing after him to make sure he was alright.

Later, the two talked alone on the sofas where they both confided that they were worried about what their families would be thinking watching at home, and admitted that a letter from home would have been good reassurance that they have their families’ support.

Having already confessed to Ashleigh earlier in the episode that he thought Mark was a “good kisser”, the two wound up back in bed together towards the end of the night, disappearing under the duvet for a quick lip-lock, before Christopher jumped over to his own bed, with a massive grin on his face.

However, it sounds like the ‘BB’ bedroom might not be the romantic wonderland that Steven and Kimberly would have us believe it is, after it emerged the house may even be shut down two weeks away from the final due to filthy living conditions.
