Imran Khan and Kareena Kapoor pair up together for the first time in coming-of-age movie Ek Mein Aur Ek Tu, co-produced by Karan Johar and directed by debutant Shakun Batra.

Imran plays the straight-laced guy who has lived his life according to his parents' expectations.

But when he loses his job, there follows a night of debauchery and he finds himself married to quick-witted hairstylist, Riana Braganza (Kareena).

Neither of them can remember quite how it happened.

Ensuing days are spent with the couple trying to get the marriage annulled – but in the process they also get to know and like one another.

This slick and breezy entertainer is more than a rom-com, showing how individuals have to learn to make their own decisions and live by the consequences of their actions.

The story of the mismatched pair who find themselves in an unlikely friendship makes for entertaining viewing.

Imran has denied that the film is similar to Whatever Happens in Vegas which also focused on a couple trying to divorce.

Kareena has three films with the Khans in the offing – after this, she teams up with beau Saif in Agent Vinod and later in the year she joins Aamir Khan for Talaash.

Also due out is Valentine's Night, a film about four couples breaking up but who meet on Valentine's Night to put the pain of separation behind them just for the night.

But what follows is an adventure with the couple discovering love – but not before a murder being committed.

The movie features Rakhi Sawant – who normally features in item numbers in Bollywood – Payal Rohatgi and Sangram Singh. Also out in February is Jodi Breakers with Bipasha Basu and R Madhavan, Tere Naal Love Ho Gaya with Ritesh Deshmukh and Genelia D'Souza and Ekk Dewana Tha with Prateik Babbar and the music of AR Rehman.
