The recent famous tie-up in Bollywood between Chotae Nawab, Saif Ali Khan, and the much adored size-zero Kareena Kapoor, seems to be losing its warmth.

It has been speculated that Kareena has started feeling uncomfortable with her beau's kids. She has been seen avoiding them.

Sources say that whenever the kids come over to Saif's place to stay, Kareena prefers staying away at her own apartment.

Bollywood's much celebrated couple, which has been ruling the hearts of many is rumored to part.

The two appear together everywhere. Saif prefers spending some quality time with his children whenever they are around, for which he gets obliged to take leave from his recent love.

In addition, Saif has been reported to be a little uncomfortable with Kareena's next film 'Short Term Shaadi', with Imran Khan, directed by Karan Johar, wherein she will appear in her size zero attire again.

To add to Saif's rages, it has been confirmed that one of the scenes will show Kareena and Imran tied together with a rope.

The film has been scheduled for a launch in India in November, this year. "I'm not at liberty to discuss anything about the film right now", said Imran.
