Bollywood actor Ranbir Kapoor has always been known to mix work with pleasure. His track record shows his closeness with almost all his leading ladies, be it Soman Kapoor, Deepika Padukone, Katrina Kaif or Nargis Fakhri.

Rumours now suggest the actor is back to flirting with his ex-girlfriend Deepika in the sets of their latest film 'Yeh Jawani Hai Deewani'.

The two have been travelling to different places for the shoot but one news is constant - their growing friendship.

After shooting in Himachal, they are now shooting extensively in Rajashtan. And later will travel together to Argentina.

Pictures from the shoot suggest unmistakeable camaraderie between Deepika and Ranbir. This led media to speculate if Ranbir is trying to renew his ties with the lady.

But there is more to this triangle saga.

Ranbir has never been able to resist the beautiful Katrina Kaif since they acted together in 'Ajab Prem Ki Ghazab Kahani'.

He spent 20 odd days in Manali shooting but when Ranbir got back to Mumbai whom did he call first? The first person he calls up is Katrina Kaif.

He had to spend some time with her immediately and the two met at a location in Pali Hill (Mumbai). This is the same evening Ranbir returned from Manali after a tough schedule.

Earlier this year Ranbir and Katrina rocked Zee Cine Awards as the two set the stage afire with their performances.

So what is Ranbir Kapoor up to? Is he just being good friends to both his ex-girlfriends or he has something up his sleeves?

Though Deepika-Ranbir are bonding well in their movie set, sources says it's just friendship. Deepika maintains that she just shares a professional relationship with Ranbir.

In far flung Thailand, where Katrina is presently shooting, she remains unmoved with all the rumours flying around. It must have filtered to her ears but she is not listening.

Maybe Katrina is used to Ranbir's habit of getting cosy with his co-stars and feels secure that he will come back to her once the movie is over.

But there's one things that still remians a puzzle- why are these top actresses falling for Ranbir’s charm time and time again?
