The R&B chart-topper appeared in good spirits on Tuesday (11 March), as he breezed through Los Angeles in a leather jacket, black jeans and his signature sunglasses.
In fact, Robin even seemed to make friends with a local photographer, who fell to the ground while snapping photos of the star.
Clearly caught in the moment, the photographer was pictured losing his footing on the street but swiftly helped back up by the 'Blurred Lines' singer.
Robin's apparent good mood yesterday may have something to do with his weekend visiting wife Paula in Canada.
Last month, longtime couple Robin and Paula made a shock announcement that they had decided to separate, although insisted that they will remain amicable.
However, the R&B crooner has been open about how he hasn't given up on his marriage and is trying to win his estranged wife back.
Soon after the news of their split broke, Robin admitted "I'm just trying to get her back, man," and even dedicated his popular track 'Lost Without You' to Paula at a recent gig.
Could this weekend reunion be a sign that the twosome might give things another go?
On Saturday (8 March), Robin was seen out and about with Paula and their three-year-old son Julian in Vancouver, where the actress is shooting her latest film, Warcraft.
The family appeared to have a fun day together, as they were spotted laughing and smiling.
Coincidentally, Paula's last tweet reads "I love my boys!!! XO", which she wrote just days before she and Robin announced their separation.
