Rihanna is reportedly "jealous" over former boyfriend Drake's closeness with Jennifer Lopez. The Work hitmaker is said to be "freaking out" as she is friends with Lopez.

"She is really freaked out about Jennifer [Lopez], especially because they're friends," a source told HollywoodLife. "She thinks of Jennifer as a mentor, so the fact that they're now Eskimo sisters is pretty overwhelming."

"Rihanna knows Drake will always love her, but she does get jealous," the source continued. "She can't stand the thought of him being with another woman."

On 17 December, Drake and Lopez were spotted enjoying some quality time in Las Vegas, where the Waiting for Tonight hitmaker put on two concerts for her fans.

Lopez shared an adorable selfie with Drake with the caption: "jloLook who rolled up to my show tonight to say hi!! @champagnepapi#lovehim #jlovegas #ALLIHAVE." Drake also shared the same photo with a heart-eyed emoji.

Also, Drake and Lopez reportedly got cozy backstage as the One Dance hitmaker could not stop hugging and flirting with her all night.

"[Drake] couldn't stop complimenting her, hugging her, and you already know he was checking out her banging body from head-to-toe," a source told Unreality TV.

"He was flirty with her the entire time... telling her how she's f***ing ageless and beautiful. He was being typical Drake, trying to make [Jennifer] fall in love with him."

Drake recently ended his romance with Rihanna while Lopez parted ways with Casper Smart.

"If the opportunity comes to date her – he would not say no," the source continued. "But he's respectful, he would pursue her if he thought she would be interested.
