sources says tabbu & nagarjun's relationship was more than husband-wife.Nag who was already in his second marriage with Amala could not declare a third marriage with Tabu (maybe out of his conscience not accepting).
But then, it seems he has been doing whatever a husband does for his wife. Not only that, he has also got an expensive house built for Tabu right next to his house. It is also heard that even Amala has understood and accepted the love relationship between Nag and Tabu with a big and generous heart. Naga Chaitanya completed his acting training in Mumbai by staying at Tabu’s home. In the interviews given to national media, Tabu has been indirectly accepting her relationship with Nag. Whether his ‘best friend’ asks or not, Nagarjuna has given everything. If she wants crores, he can shower them
