Bollywood stars have always done cameos in films for the sake of friendship. From Amitabh Bachchan, Aishwarya, Shahrukh Khan, to Kareena, Sanjay Dutt, all have done it at some point or the other.

But OSO girl Deepika Padukone who celebrates her birthday today is still not ready to become like one of them. Even though Shah Rukh Khan gave her the first break, the actress can't afford to be charitable with him. She readily accepted the cheque which SRK paid her for an item number in 'Billo Barber'.

Billu Barber is SRK's home production directed by Priyadarshan, starring Irrfan Khan, Lara Dutta and Shahrukh Khan.

On the other hand Kareena Kapoor and Priyanka Chopra returned the cheque of 40 lakh which Shahrukh offered them for appearances in the movie.

Bebo and Priyanka returned it by saying that they have done it for Shahrukh as he is their close friend and they share a good personal and professional relationship.

On the other hand Deepika deposited hers in her bank.

A source close to Deepika defends her, "Kareena and Priyanka can afford to forego their payment as they are established actresses; Deepika is starting out. She wouldn't hear about being paid for her debut film as she felt obliged to Farah Khan and SRK for her break."

Well, be it love or work, Deepika always has business on her mind.
