Is Rob Kardashian the Father of Blac Chyna’s unborn baby

Blac Chyna had no choice but to take paternity test after Rob Kardashian accused her of cheating. The question is, is he the father? Blac Chyna was seen in the preview, Rob & Chyna, telling her guy friend that a part of her wants to take a paternity test which sounded ridiculous to him.
Meanwhile, not only did Rob accuse Blac Chyna of cheating, the ridiculousness of it is the fact that he believed she cheated with her ex, Tyga, who has been dating Rob’s sister, Kylie Jenner. Rob was seen in the next clip joking apologizing to Blac Chyna and gave her a bouquet of flowers which she threw in the pool. Another clip showed Rob saying ‘I love you’ to Chyna. Is he the father?
