Bollywood actress Mallika Sherawat promises her new movie "Bachke Rehna Re Baba" will be wildest, funniest and sexiest film of the year.

The movie, to be released across India Friday, will "rock Delhi and take the audience for a joyride", Mallika told reporters here Thursday.

"'Bach Ke Rehna Re Baba' has all the elements to attract movie-goers. Its unchallenging comedy laced with sexy scenes will provide pure entertainment to the audience," she said.

"It's a sex comedy and will charm the old and young alike. You just need to go and enjoy the fun."

Speaking about her experiences while acting with Rekha, who plays a leading role in the film, Mallika said she had been nervous when she signed the movie.

"I was absolutely nervous and felt overshadowed by Rekha's personality. But she turned out to be a cool lady and made me feel comfortable," said Mallika, who gave tips on kissing to Rekha for the film.

"While I gave her smooching tips, she gave me beauty tips," she said with a smile.

Directed by Govind Menon of "Khawhish" fame, the movie also has Paresh Rawal and Satish Saha.

Newcomer Karan Khanna, the nephew of Vinod Khanna, plays the role of Mallika's lover.
