Rihanna has definitely put on some weight - it's not clear whether it's PREGNANCY weight . . . or just GROWN WOMAN weight.

Rihanna's been filling out ever since she started dating that Saudi billionaire. His name is Hassan Jameel, whose billionaire family is believed to be one of the wealthiest in the world. He's the deputy president and vice chairman of the family-run business, Abdul Latif Jameel, one of the world's largest companies, and is a key investor in Toyota. His family is reportedly worth $1.5 billion.
