Bollywood actor Vivek Oberoi seems to have taken a fancy to following star couple Aishwarya Rai and Abhishek Bachchan. He did it yet again here Thursday evening, almost a fortnight after reportedly found tailing them in Mumbai.

Vivek made an unexpected late entry at the premiere of "Rann", at the PVR Select Citywalk, where Aishwarya and Abhishek were present for the red carpet premiere of the Amitabh Bachchan starrer.

Vivek, who was linked with Aishwarya earlier, arrived hastily at the venue half an hour after the premiere had begun, adjusting his cuff links and with his bodyguards in tow.

The actor bumped his leg on a barricade before he was ushered on the red carpet - making a lonesome sight with no one to walk beside him. The star cast of "Rann" - Riteish Deshmukh, Gul Panag, director Ram Gopal Varma apart from Amitabh - had already moved into the theatre by then. Aishwarya and Abhishek were also in the multiplex.

"It's strange to see Vivek here. We don't know if he has been invited here or has come over just because he is in the capital for an event. He has one lined up for Friday, " a source who was there, told.

Vivek was reportedly an uninvited entry at Hrithik Roshan's birthday bash early this month at Shah Rukh Khan's house Mannat in Mumbai, where the Bachchan couple was present.

He was also spotted chatting with Big B and his wife Jaya at a recent awards function where Aishwarya and Abhishek were noticed sitting at a far distance.

Releasing Friday, "Rann" has been co-produced by Madhu Mantena and Sheetal Talwar.

Also starring Paresh Rawal in a pivotal role, it is about the conflict between business and conscience in the electronic media these days.
