The audio launch of Arya-Nayanthara's most-awaited film "Raja Rani" (King, Queen) is all set to take place at Sathyam Studios on 23 August.

Celebrities including Arya, Nayanthara, Jai, Sathyaraj, Nazriya Nazim, and Santhanam, all of whom have worked in the film, as well as "Raja Rani" director Atlee, producer AR Murugadoss and music composer GV Prakash are likely to attend the grand event.

Atlee has also invited Rajinikanth for the audio launch. He met the legendary actor at his residence and requested him to attend the event. The superstar reportedly appreciated the director for his innovative concept of the invite. It is not clear if Rajini would show up for he occassion on Friday.

When the first teaser of "Raja Rani" was released a few months ago, it created a stir. It has to be recalled that a wedding invite of Arya-Nayanthara was doing rounds on the internet, paving way for speculation that the duo are getting married in real. Later, the makers of the film confirmed that the lead actors of "Raja Rani" were not getting married and that the invite was just a publicity stunt to promote their upcoming film. Following this, a small teaser showing Arya-Nayanthara quarreling and fighting in their mirror images was released. The teaser created a buzz among audience.

Music composer GV Prakash, who is basking in the success of "Thalaivaa" music, has helmed the soundtrack for "Raja Rani." The album has six songs and one love theme song.

Recently, a single track from the film was released in a popular FM channel. The track - "Marriage made in heavennu evan sonnaan,  Kalyanam kaleejunnu Gajaa sonnaan" - has already become popular among the youth. Overwhelmed with the response received for the first track, the "Raja Rani" team released the second track - "Chillena" - on Wednesday (20 August).

"Raja Rani" is the debut venture of Atlee, who has earlier worked as an assistant in Rajinikanth's 2010-blockbuster "Enthiran". The romantic-comedy film is produced by AR Murugadoss in association with Fox Star Studios. This is their third Tamil project after "Engeyum Eppodhum" and "Vathikuchi".
