The couple has been getting serious, with Life & Style reporting that Jennifer had already introduced her eight-year-old twins, Max and Emme, to the Degrassi actor.

"Drake has been hanging out at Jennifer’s new house in Bel-Air. He has been there several times and is getting to know her kids,” a source told Us Weekly. “They all have a lot of fun together. Her kids really like him and they know all of his songs. They like having him around.”

Meanwhile, Drake's ex Rihanna is not happy about the new relationship, calling Jennifer "desperate."
