Trouble between karishma and sanjay?

Is there any trouble between actress Karishma Kapoor and her hubby Sanjay Kapoor? Karishma's recent visit to Mumbai has made the rumour mills working overtime again.
As per rumours, Karishma recently traveled UK along with her little daughter and mom Babita. Karishma also spent some quality time with younger sis Kareena and her beau Shahid who were in the UK for their 'Rockstars' world tour. But husband Sanjay neither accompanied them nor did he join them later on. According to sources "Things are not working out between Sanjay and Karishma. It's his habits that are causing the strain."
According to a few sources Karishma wants to stay with her mom indefinitely in Mumbai. She has also planned to enroll her little daughter Samaira in a playschool in Mumbai. Sanjay Kapur is a Delhi based businessman while Karishma prefers being in Mumbai where her entire family lives. This is only one of the many differences that have cropped up between Sanjay and Karishma. It is also being said that Sanjay lives an extremely flamboyant lifestyle in Delhi to which Karishma who is a simple girl cannot adjust.
Also Karishma wants to make her comeback in film, and Sanjay doesn't want his wife pose before camera again. So there is difference. However neither Karishma nor Sanjay nobody have confirmed the rumour.
