But much before that, Isha Koppikar started off her acting career down south in 1998. She was 22.

18 years after her claim to fame with 'Khallas' item song, this is how Isha Koppikar looks now. The actress is enjoying her motherhood, clearly!

On her birthday, we take a quick look at a few more interesting facts about Isha, you probably didn't know:

Did you know Isha Koppikar has a black-belt in Taekwondo? She has also learned Hapkido - the highly stylised Korean martial art of self-defence.

Besides 'Khallas' from Company, Isha Koppikar has also done several item numbers including 'Ishq Samundar' from Kaante.

Isha Koppikar has worked in five different film industries - Bollywood, Tamil, Telugu, Kannada and Marathi films.

Isha Koppikar has changed the spelling of her name twice, first to Ishaa Koppikar and then to Eesha Koppikhar. However, in 2015, she has reverted to the original spelling of her name.

Isha Koppikar wishes to play Kiran Bedi or Indira Gandhi on-screen if a biopic on the respective great personalities is approached to her. She had told mid-day, 'I haven't exactly thought about it. I am fond of strong characters... I'd like to make one on the lives of Kiran Bedi or Indira Gandhi. Or perhaps any character that you can choose from mythology.'

Isha Koppikar is an absolute foodie, but a conservative one. 'My biggest adventure in a restaurant is limited to eating a duck and rabbit meat. I have not eaten a crocodile,' she had told mid-day once.

A true-blue Mangalorean, Isha loves her spicy tangy fish curry with rice. The actress does believe in 'eating healthy' but let's go when she wants to.

'I love the full-bodied taste of Mangalorean food. I grew up on Konkani fish curry and rice. One of my favourite dishes is Batata Saung. It is a spicy potato curry that gets its red colour from Byadagi chillies. I remember craving for it when I was away from home for my school camps. I had gone to Nepal for a school picnic when I was in the sixth standard. My desire to eat Batata Saung reached such a point that I phoned my grandmother from the hotel's reception, saying, 'Annamma, I want to eat Batata Saung once I come home',' Isha revealed to mid-day.

Isha Koppikar is a complete fitness freak and she keeps her diet plan healthy. Shedding some more light on her food habits, she said, 'Breakfast is usually egg whites and bread. I also have oats, quinoa or phulkas. Between breakfast and lunch, I have a fruit and a cup of green tea. I have replaced white rice with red rice in my daily diet as it's full of fibre. For lunch, I have red rice with a vegetable and fish or chicken curry. I don't overdo the protein intake. I balance fish, chicken, dal or paneer in a meal. Paneer I have only on days when I am vegetarian.'
