While Kareena Kapoor is busy painting the town red with her latest arm candy, Saif Ali Khan, her now ex is still trying his best to get back together.

Kareena, however, is not in a mood to indulge any efforts on Shahid's part, and clearly demonstrates that she has moved on – her recent birthday celebrations with Saif being the latest slap on Shahid's sorrowful face.

Shahid is currently in Toronto, shooting for Aziz Mirza's movie, but he is expected to return to Mumbai soon.

A source, on condition of anonymity said, "Shahid is hopeful that Kareena will get back to him. He has been sending her messages and e-mails, but she has not responded as yet to any of them."

This has led to Shahid withdrawing into a shell, and he has been unusually quiet and reserved on his sets.

Rumours earlier had it that Shahid was planning a surprise birthday party for Kareena, and had even made arrangements with her sister, Karishma.

According to the source, he dropped the idea when he saw the photographs of his beau and the Chotte Nawab, splashed all across the media. Apparently, Kareena has gone back to her non-vegetarian diet, something she had given up for Shahid. In fact, she is not even speaking with him at present.

"Kareena may soon ask, 'Shahid, who?' We never thought the relationship would die so soon," the source continues.

Shahid, however, has not given up, adds the source. Kareena and Shahid will be seen in 'Jab We Met', a film by Imtiyaz Ali, due for release soon.
