After rumours of Ranbir Kapoor considering his Rockstar co-star Nargis Fakhri for a serious relationship, the Kapoor dude has been spotted with Katrina Kaif in his sports car by an onlooker. Ranbir has been flirting openly with Half Czech half Pakistani newcomer Nargis during the shooting of Rockstar. The couple were even reportedly spotted canoodling with each other. According to reports, Ranbir had even confided in one of his close friends that he might take his relationship with Nargis further.

It seems like Ranbir can't stick to his decisions for long. That's probably why he and Katrina, who allegedly developed differences sometime back, were seen together.

A source told Mid Day, "Ranbir is really fond of that car and loves to drive in it. This time, however, he got caught driving around Juhu with Kat by his side. Since the windows didn't have sun film, Katrina's side profile was captured by an onlooker who passed the car."

Well, Bachna Ae Haseeno!
