Bollywood actress Karisma Kapoor Tuesday denied reports that her younger sister Kareena is set to tie the knot with beau Saif Ali Khan towards the end of 2012.

"Kareena is not getting married anytime soon, " Karisma said here.

Rumour mills have been abuzz with information that the couple - 'Saifeena' - is ready to settle down, and that their nuptials would happen at a palace in Bhopal in royal style.

A report also said that Kareena's wedding trousseau would be designed by Ritu Kumar

But Karisma's denial proves otherwise.

The charismatic 37-year-old was here to promote skincare product Olay Total Effects, which she feels is the reason behind her "ageless beauty".

"When I started using this product in 2007, it was a life-changing experience. I strongly believe that if you look good, you feel good, and that's just what happened with me, " said Karisma, who will be seen on the big screen once again soon.

The actress, who has done films like "Dil To Pagal Hai", "Biwi No.1" "Raja Hindustani", and "Zubeidaa", was last seen in "Mere Jeevan Saathi" which released in 2006.

She has now teamed up with model-turned-actor Rajneesh Duggal for Vikram Bhatt's film titled "Dangerous Ishq".

"I can't speak much about the film but yes, I am doing it because I think the time was right, " said the actress, who looked stunning even in a simple black top and a pair of dark blue jeans.
