The singer and her Real Madrid star beau were pictured in a car together on Saturday night as they arrived at Giorgio Baldi restaurant in Santa Monica.
While RiRi wore bright red lippy to match her flame-coloured hair, and an all-black outfit, she stood out in the backseat but failed to smile.
Meanwhile the footballer wore a denim jacket and white t-shirt as he appeared to chat to her while making their way past photographers.
While the pair are yet to confirm romance rumors, it’s the second time they have been snapped together in so many days.
The star enjoyed a night at 1OAK nightclub in West Hollywood on Thursday night with footy ace Karim also in attendance.
RiRi was later pictured leaving the club through a back exit and jumping into a car with her entourage.
Meanwhile, striker Karim left through a crowded front exit.
According to Us Weekly magazine, the pair are enjoying each other’s company but are not official just yet.
A source said: “She’s not officially dating him.”
Tongues first started wagging the pair could be more than just friends when they were spotted dining together at 24-hour restaurant Coppelia in New York last week.
We have contacted the star’s reps for comment.
