Ranbir-Katrina caught kissing on a flight

Couple seen getting cosy on flight

Ranbir Kapoor and Katrina Kaif have always denied being involved. But they can't do so anymore. The duo indulged in some serious PDA on an international flight LH 576 from Frankfurt to Mumbai on Sunday night. 

Radio One Host Malini Agarwal reports on her blog (www.missmalini.com) that her friend witnessed the lovebirds first hand, as she was also seated in the same row of the first class cabin. 

Ranbir and Katrina were seen holding hands and they even exchanged a kiss. 

According to the eyewitness report, "The first class had many European businessmen, and not too many passengers recognised them. Katrina was wearing a casual T-shirt and jeans and had no make up on. 

Initially she kept looking around to see if
there would be any familiar Indian faces, but when she saw that wasn't the case, she got comfortable in her seat and started talking to Ranbir. 

After the flight took off, they cosied up and RK was seen planting kisses on her cheek and she didn't seem to mind at all." 

Apart from enjoying the first class services, they also used the time to get some work done. "There were a couple of scripts piled up on their table. 

They both engrossed themselves in them. At one point they were even reading out their parts out loud, as though they were rehearsing. Ranbir later called for some blankets, but neither of them were seen taking a nap." 

RK was in Amsterdam shooting an ad for a newly endorsed product, while Kat had joined him to spend some time. The two were planning to get away from the city for a while, and this seemed like a perfect opportunity. 

Especially since Salman Khan is out of the country shooting in Bangkok for a 50-day schedule.
