Kareena Kapoor and beau take a break from their Swiss hols for one day to return to Pataudi to celebrate Saif's dad's 70th b'day

Kareena Kapoor and beau Saif Ali Khan who are holidaying in Gstaad in Switzerland, returned to Mumbai for a day (more than 20 hours in travelling time) to celebrate his father Mansoor Ali Khan Pataudi's 70th birthday (Jan 5).

Annual ritual

Says a source close to the couple, "This is part of their annual ritual. But this year, their vacation was split. They flew in from Zurich for Pataudi Sr's birthday and then flew back the following day.

Since both are busy with their respective shootings, there was no other way or else, this break would not have been possible."

The couple flew out on December 31 and are booked at the Palace Hotel in Gstaad, Switzerland till January 14.

They didn't even check out of the hotel and left most of their belongings there and travelled only with their bare essentials.

Saif, sisters Soha and Sabah and mother Sharmila had planned a special evening for Pataudi in their ancestral home.

Says an insider, "Bebo is very fond of her would-be parents-in-law and was part of the planning for the birthday celebrations right from the beginning."

Special presentation

Sharmila had put together an audiovisual presentation on her husband that was screened at the bash.

The video included memorable moments of her husband's great milestones in cricket and recorded bytes from close friends and family talking about their interactions with Tiger (Pataudi's nick).

Saif and Bebo ordered a special three-tiered birthday cake and gifted emerald and diamond earrings to Sharmila. The pair flew back on Thursday early morning.

Private occasion

Sharmila says, "We had a small party for him. It was a very special occasion for a very private person (Pataudi) with close friends and family including all our children. The grandchildren couldn't come as they were in Singapore."
