Ranbir Kapoor and Alia Bhatt: Bollywood toasts star couple on wedding

Bollywood stars Ranbir Kapoor and Alia Bhatt have tied the knot in what is being dubbed one of the biggest weddings of the Indian film industry.

Many stars were among close family and friends at the low-key event, held at the couple's Mumbai home.

Their names are trending on Twitter and social media is brimming with good wishes for them.

The actors are among the most popular faces of Bollywood, with millions of fans the world over.

The wedding was confirmed by Kapoor's mother Neetu Singh - a famous Bollywood actor herself - on Wednesday. It took place at Kapoor's family home, a bungalow tucked away in the affluent Bandra neighbourhood of Mumbai.

"Today, surrounded by our family and friends, at home... in our favourite spot - the balcony we've spent the last five years of our relationship - we got married," Bhatt posted on social media.

Kapoor and Bhatt's first film together - Brahmastra - will release in theatres later this year.

Bollywood superstar Amitabh Bachchan, their co-star in the film, took to Instagram to wish them "all the Love, Luck and Light as they gear up to embark on a very special journey in the coming days".

Filmmaker Ayan Mukerji, who is a close friend of the couple and the director of Brahmastra, wished them all the best.

"Wishing that the best of Energies and all the Blessings, all the Joy and all the Purity, surround them as they enter an amazing new chapter of life, together forever," he wrote in an Instagram post.

Filmmaker Karan Johar also congratulated the couple on Twitter.

This has heightened the excitement of fans, many of whom have been flocking to catch a glimpse of the stars and heavy security was deployed outside Kapoor's residence on Wednesday.

For days in the run-up to the wedding, social media was abuzz with speculation about what the stars would wear to who would be in attendance.

But the couple decided to keep the celebration an intimate affair, choosing to spend it with close friends and family - who include some of the biggest faces of Bollywood.

Kapoor's cousins - celebrity sisters Kareena Kapoor Khan and Karisma Kapoor - and several others attended their mehndi, or henna ceremony, on Wednesday.
