It's not always 'sunny side up' for Bollywood stars and this was lately seen when our very own heartthrob Ranbir Kapoor was detained at the Mumbai airport yesterday morning.

Apparently, the actor who returned from London around 12.30am on May 5, was carrying imported good such as perfumes, clothes and footwear worth 1 lakh.

Instead of declaring the goods before the customs officials at the Red Channel, Ranbir just walked through a passage which is strictly used only by officials and airport staff.

The actor's luggage was then checked and he was taken aside for an enquiry by the authorities. Ranbir said that he was unaware of the customs rules and regulations.

After being detained for over 40 minutes, he was asked to pay a fine of 60,000. Once the actor paid the fine he was allowed to leave with the goods.

Well, this is not the first time that celebrities have broken airport rules. In the past, Bipasha Basu, Minissha Lamba and a few others have been fined for customs violation as well.
