Hollywood diva Liz Hurley and her NRI boyfriend Arun Nayar arrived at the majestic Devigarh Palace in Udaipur to celebrate the latter's birthday, amid speculation that the two may exchange wedding vows after over two years of romancing.

This picturesque heritage town, nestled in the Aravalli hills, has seen many celebrations, but this time it may well witness one of the most-talked about love affair culminate at the holy altar.

The 'bedazzled' star, accompanied by her son Damien, and Nayar arrived late on Thursday night and drove straight to the palace-turned hotel, 30km from Udaipur, amidst tight security.

A host of high-profile guests accompanied the star-couple and more close friends and relatives trickled in on Friday to take part in the birthday bash of Nayar, a London-based businessman.

The private event has, however, evinced keen interest among the media as it is speculated that the two may tie the nuptial knot at one of the two lavish parties the 39-year-old Hollywood star is throwing for her boyfriend, who is turning 41.

The glamorous couple have booked about two dozen rooms and more than 50 close friends and relatives are expected to take part in the celebrations, palace sources told PTI. However, they were tight-lipped when asked about the wedding plans and maintained that it was a purely personal affair.
