Archita Kashyap, New Delhi: They are Bollywood's hottest couple these days, and they're making no effort to hide the fact that they like having a good time.

Bachelor-again Saif Ali Khan and recently-single Kareena Kapoor have surprised everyone by hooking up and partying hard. In the past few weeks, the couple has been spotted on several occasions, dining together or just hanging out.

What's surprising is the fact that they don't seem to care about the prying paparazzi. Why else would Saif show up publicly on the sets of Sa Re Ga Ma to pick up Kareena who was there as a special guest on Friday?

Why else would they choose fairly public places like Zenzi in Bandra, or the J W Marriott in Juhu to hang out at?

Freshly-split from Shahid Kapur, her boyfriend of over four years, Kareena celebrated her 27th birthday on Friday with a small party for select friends including Saif.

The chote nawab for his part, has been single for months now, since his break-up with girlfriend Roza. The actor has, since, been linked to Bipasha Basu and Dia Mirza.

Saif and Kareena were last paired together in J P Dutta's LOC, which tanked at the box-office. Both extremely temperamental individuals, they didn't quite hit it off until recently, while shooting for Yash Raj Films' Tashan.

Shahid and Kareena have a day's shooting still left for their new film Jab We Met which releases in October. Suffice to say, it will be an awkward day on the sets for both.
