Ajay Devgn turned 50 on April 2.
He celebrated his birthday with the trailer launch of his film De De Pyaar De, also starring Tabu and Rakul Preet.
At the trailer launch, Ajay felt female actors enjoy a longer shelf life now.
Ajay, who is sharing screen space with his '90s co-star Tabu in De De Pyaar De, said the change has come in the past decade.
"Today things are different than what they were ten years ago, in terms of shelf life of female actors. Now they have more shelf life or as much shelf life as male actors. There is no difference today, but earlier there was," Ajay told the media.
"We have Tabu and Kajol and others working still," Ajay added.
Ajay cut his birthday cake at the event and said age is just a number.
"Ageing is about how you feel and not about the number," the actor said. "All my contemporaries are so fit. I think staying fit must be a conscious decision because the intention was that what you could do 25 years ago... you could still do it. I am happy that I can do exactly that."
Ajay refrained from commenting on the #MeToo allegations against his De De Pyaar De co-actor Alok Nath, who writer Vinta Nanda had accused of rape last year.
When Producer Luv Ranjan was asked to comment on the same, Ajay intervened saying, "This is not the right place to talk about it."
"And jinki aap baat kar rahe hai woh film uske pehle complete hui (the film was completed before the allegations surfaced against the concerned person).
De De Pyaar De releases on May 17.
