It looks like Bollywood actor Vivek Oberoi will never learn his lessons, here's why.

Salman Khan is gearing up for the release of 'Ek Tha Tiger' and his not-so-good friend Vivek Oberoi has signed 'Sher'.

Referring to the titles of their upcoming movies Vivek Oberoi took a dig at Salman Khan, saying 'Sher' is bigger than 'Tiger'.

It is a common knowledge that Salman Khan and Vivek Oberoi are arch rivals of the industry. The reason being, the long ago fight over ‘common love interest’ – Aishwarya Rai Bachchan.

Vivek had called a press conference many years ago to inform eveyone that Salman Khan has been threatening and harassing him for stealing his girlfriend.

Since then there was no love left between the two. Even though Vivek came to his senses and apologised many time publicly, Salman did not budge.

In meantime, Aishwarya has ditched both the actors and has moved on in life with husband Abhishek Bachchan and her new found motherhood, her two past lovers have maintained their tiff!

The most recent remark comes from Vivek Oberoi. Salman and Vivek both have their forthcoming release with somewhat similar titles - Salman’s ‘Ek Tha Tiger’ and Vivek’s ‘Sher’.

Commenting on competition Vivek says, “All of us are wildlife enthusiasts hence such titles. Don’t know about it much, but as far as I know, ‘Sher’ is bigger than a ‘Tiger’.”

Now that’s a direct hit at the man, Salman Khan. However, remind the actor that Salman will have yet another ‘sher’ release, titled ‘Sher Khan’. Vivek quips, “It is a happy thing, seems like a city of ‘shers’.”

Considering the series of comments, Vivek sounds overconfident, as the shooting of ‘Sher’ has just kicked off and the actor is already taking pot shots at Salman’s close to release ‘Ek Tha Tiger’.

Salman Khan's 'Ek Tha Tiger' is one of the most-awaited movies of Bollywood in 2012. Salman is playing the role of a RAW agent in the Yash Raj film, which features Katrina Kaif alongside him. This romantic thriller, which is directed by Kabir Khan, is scheduled to release on 15 August, 2012.

However, Vivek Oberoi's 'Sher' is an action-thriller, which is directed by Soham Shah. When reminded about Salman's other upcoming film titled Sher Khan, Vivek said, "It is a good thing... the city is filled with Sher(s)."
