International singer Adele has made headlines after a video of her crying during her recent Las Vegas concert went viral. She was moved after helping two fans reveal the gender of their unborn child on stage during her performance at the Colosseum at Caesars Palace. Adele, who is 35 years old, said in a video posted on social media that no one is allowed to hold signs during her shows at the Colosseum, but that she made an exception for the couple.
