Bipasha Basu has had a long shooting stint in Goa of more than a month and a half for All The Best, which was followed by one more shoot in Hyderabad. But now she is back in tinsel town and is seen taking extra time out to help her younger sister Rinnie.

A source close to the actress states, "Bipasha is very much elder to Rinnie and she is taking full responsibility of looking after her.

Rinnie would often be seen accompanying Bipasha on her shoots in Mumbai since she was studying in a Mumbai college. But now she is planning to go abroad for higher studies. Bipasha is therefore ensuring that before Rinnie leaves in September for UK for her studies, everything required for her falls right in its place.

Bips has the experience of staying abroad for a long period when she was on a modeling assignment with the Ford Supermodel Agency.

She is using that experience to help Rinnie now. She is, in fact even making a list of things that Rinnie may require in her house there."

After all this, Rinnie must be definitely saying, "I am really lucky to have a sister like Bipasha!"
