India, July 5 -- Bollywood superstar Aamir Khan is set to marry longtime partner Gauri Spratt in an intimate ceremony at his Bandra residence in Mumbai on Sunday.

The couple have known each other for nearly 25 years but began dating only two years ago.

Aamir made their relationship public on his 60th birthday during a media interaction, introducing Gauri and confirming they were together.

Private ceremony with close family

The wedding will be held at Aamir Khan's Bandra home with around 150 guests expected to attend.

Several relatives are also likely to travel from overseas for the celebrations.

Gauri Spratt's six-year-old son from her previous marriage, who has largely stayed away from the spotlight, is also likely to attend.
