Scott, who split from partner Kourtney Kardashian earlier this year, and Tyga - whose romance with Kylie Jenner has reportedly been under strain recently - were invited to the family bash on Thursday (26.11.15) but were reportedly quite uncomfortable.

A source told HollywoodLife.com: "They were two twins joined at the hip. It was like they were the two giant elephants in the room that everyone was talking about in their minds. They were definitely nervous. They both were fully aware that they haven't been the best of boyfriends this year and being around all the Kardashians made them feel a bit woozy."

However, the family put their troubles behind them to put on a united front at the celebration.

And Scott has reportedly vowed to clean up his act to win Kourtney back and be a good father for their children Mason, five, Penelope, three, and Reign, 11 months.

The source added: "He told her that his New Year's resolution is to be sober and a better father to his children and a better boyfriend to her. Scott's made promises like this before and it appears that Kourt's trusting he's going to be a man of his word."
