Sanju ensures Maana has a happy b'day, gets friends to spend time with his wife and even leaves behind a birthday gift

Sanjay Dutt won't be in town today as wife Maanayata (who is expecting twins) turns 32. The doting husband may be in South Africa but left her a surprise gift and also had their family friends spend time with her on her janamdin. Not one to be outdone, Maana is also planning to fly down to Oman to surprise her man on his 51st b'day -- provided her gynaecologist gives her permission to travel.

Says a source close to Dutt and Maanayata, "When Sanju left for South Africa in the first week of July he had given his business manager Dharam Oberoi a beautifully wrapped parcel and told him to give it to Maana on her birthday. It appeared to be a jewellery box and looked like a diamond set (Maana loves diamonds).

Last night, Dharam, his daughter Neha, her friend Mimi, Apoorva Lakhia, Sohail Maklai and Bunty Walia went to the Dutt residence in Bandra and gave Maana a surprise party. They brought a huge chocolate cake along and took her out to dinner. Sanju didn't want Maana to be alone on her birthday."

Dutt is currently doing a recce for his first production Rascals (directed by David Dhawan) in South Africa, Morocco and Oman. "Maana is in her fifth month of pregnancy and South Africa is almost 10 hours away. Maana won't be able to fly down there.

But she's determined that on Sanju's birthday (July 29), she will fly down to celebrate it with him in Oman, which is only two hours away. That, too, if her doctor gives her permission to travel. Sanju and Maana are in touch every day and miss each other terribly."

The buzz is that Dutt might just drop in for a surprise visit today. "When Sanju was canvassing for the Samajwadi Party in Uttar Pradesh, he flew in for a night by jet and sang Khuda Jaane (the Bachna Ae Haseeno track) to Maana as he was missing her a lot. Last year, he gifted her a limited edition Corum watch on her birthday."
