Genelia D'Souza and Virat Kohli for Fastrack

We start off with bubbly Bollywood sweetheart Genelia and one of India's most desirable cricketers Virat Kohli getting it on -- in an elevator, before seeming to go their own ways. The commercial seems to reflect watches and accessories brand Fastrack's catchphrase 'Move on'.

Whew! Steamy stuff! How convincing do the two look on screen? We're buying into it!

Next we have Dippy and Purab in the roles of beauty and the loveable geek, respectively, for coffee giant Nescafe.

Dippy is sizzling as usual and Purab suits the role to the tee in this commercial series. Karan Johar playing a cameo only adds to the humour, but the lead couple are as cute as they come. Hmmm -- what's brewing!

King Khan and wife Gauri show us that a longlasting marriage can still be romantic in this advert for D'Decor fabrics. Shah Rukh pursues and Gauri resists, until a kiss on the forehead seals the deal. We're truly touched!

Lovebirds Bebo and Saif have also done a whole series of commercials for Airtel cellular services and this Diwali special was one of the more romantic ones. She tricks him and flees, he pursues in true filmi style, ultimately pulling her into an embrace with a little help from his mobile.

Isha Sharvani is charmed into dancing by 'Twinkle Toes' Roshan in this lighthearted little skit, all because she can't resist the chocolate-y goodness of Hide & Seek biscuits. Or are the biscuits just an excuse (wink)!

He's late and she's angry, until with a snap of his fingers the street they're on transforms into a romantic wonderland with fairy lights, a candlelight dinner, a live serenade and fireworks. Makes you believe that Preity and Neil are as good a match as the Morellato watches they're sporting!

Both veteran actors and married to boot -- we're not surprised that Big B and wife Jaya put on an entertaining performance for jewellery giant Tanishq.

In a bid to impress, he does his homework and delivers a diamond necklace with a knowledgeable speech, but she wants bangles too!

Two lovers out camping, with snuggles and banter over tea and the telephone -- mobile telephone, that is! The chemistry between Vidya and Madhavan was the talk of the town when their ads for Airtel were launched and it won't be soon forgotten!

The pretty Kalki woos the cute Khan with an imaginary bottle of Coca-Cola in this entertaining advert -- and he in turn woos her with a real one.

Sweet concept and sweeter on-screen couple, don't you think?

The Khiladi takes the sedate Amrit for the ride of her life through a busy marketplace chasing his favourite aerated drink and lands up in hospital. But he's still whispering sweet nothings to a bottle of Thums Up and gets his just deserts! Think these two make the sparks fly?
