Rumored-to-be-pregnant Selena Gomez recently said "no" to alcohol while on a dinner date with Justin Bieber's best friend, Jaden Smith, in London. Her refusal to drink alcohol sparked another round of speculations that the "Come and Get It" singer has been confirmed to be pregnant with her boyfriend, Justin Bieber.

While on a trip to London for her promotional activities, Selena Gomez went on a dinner date with Jaden Smith, who is also Justin Bieber's best friend, and his father Will Smith at Hakkasan restaurant on Thursday.

During her time in London, pregnancy rumors have run wild after Selena Gomez cancelled her Twitter chat with fans due to a mysterious illness.

Just a day before her dinner date with Jaden Smith, Selena Gomez wrote on her twitter and said, "Sorry to everyone for having to cancel today. I am not sure if I am sick or ate some bad food but, I feel horrible. I am going to take the rest of the day and try and get better for tomorrow. So Sorry :( Love you guys."

Although Selena Gomez later admitted that her sickness was most likely just a cold and not a sign of her pregnancy with Justin Bieber, Selena Gomez's choice of food and drink on her dinner date again triggered more speculation that she may indeed be pregnant.

Since the legal drinking age in the U.K. is just 18, Selena Gomez, 20, could have easily ordered and had a few drinks.

Selena Gomez's refusal to drink alcohol that night led people to think that the reason for her refusal was because she did not want alcoholic content to affect her baby's health.

However, fans came to her defense by citing possible reasons for her reluctance to order alcohol. Some say that she was simply used to the legal drinking age of 21 in the U.S. Others speculate that she probably did not want to drink alcohol when Jaden Smith, 14, could not.

It is very likely that Selena Gomez was simply not feeling well and did not want alcohol to worsen her symptoms.

After the dinner date, Selena Gomez and Jaden Smith were reported to have been partying at a nighclub in London.
