It is the biggest day of Imran Khan's life. The Jaane Tu... star is getting engaged to his long time sweetheart Avantika Malik in a grand ceremony to be held tonight.

Though it is going to be a lavish affair when the two exchange rings at Avantika's family farmhouse in Karjat, Imran has planned to keep it as a close family affair. The actor says that he doesn't want his engagement to be a "tamasha"!

Talking to a news daily about the special day, Imran said, "We have invited 300 guests, mostly family and close friends. We wanted to keep it personal."

To make the entire day a special outing all the guests have been invited to a daylong outing that includes a brunch, followed by the ceremony and dinner in the evening.

As for the guest list, Imran revealed, "Aamir Khan will be there with wife Kiran, so will Mansoor (Imran's uncle) and family." His father Ajit Pal is coming from the US. Though his parents are divorced, he is on amicable terms with his father. Imran's in-laws-to-be, Ranjev and Vandana Malik are also very ecstatic about their daughter's big day.

There are few big film personalities who are going to attend the ceremony and their name are Sonam Kapoor, Karan Johar, Deepika Padukone and Abbas Tyrewala. Though 'friend' Ranbir Kapoor is conspicuously missing from the list.

We hear that that Ranbir dated Imran's girl Avantika for five years before Khan came on the picture. He is also believed to have given the event a miss in order to avoid any awkward rendezvous with Deepika Padukone. He is currently shooting in the US for Anjaana Anjaani and will not be back in Mumbai after the schedule of the film ends mid-February.

Buzz is that Imran surprised Avantika by gifting her a swanky new red fancy car, which has always been her dream car. Talking to a leading daily Imran tells, "I knew that Avantika had always wanted this car, even six years back when we were studying in the US.

So, I just knew that I had to buy one for her and this occasion was just the perfect excuse. Since the car has just launched, I had to convince the top bosses to let me have one, way before it actually hits the roads in a few months time. That took quite an effort. But her smile made it all worth it."

Well, we would just say - Congratulations Imran and Avantika. May God shower his choicest blessings on both you.
