After making their relationship official in a traditional roka ceremony, Priyanka Chopra and Nick Jonas hosted a pre-wedding party in Mumbai on Saturday. The star-studded event saw many A-listers of Bollywood along with the Ambanis coming under the same roof to bless the couple on their engagement.

Several celebrities like Ranveer Singh, Hrithik Roshan, Alia Bhatt, Sonam Kapoor, Masaba Gupta, Shilpa Shetty Kundra, Diana Penty, Neha Kakkar, Bipasha Basu, Preity Zinta, Anushka Sharma, Sophie Choudry and Malaika Arora sent in good wishes to the couple.

People were expecting Deepika Padukone to arrive at the event along with her long-time boyfriend Ranveer Singh to wish Priyanka and Nick. But her absence has got many tongues wagging. And it will be hard for many to swallow the fact that Priyanka chose to invite Ranveer for the bash but left out Deepika for some reasons that are yet to be known.

"Deepika has always been supportive of Priyanka and she would have definitely gone to wish her if she was invited. In fact, everyone knows Ranveer and DP are a couple and will walk down the altar this November. So, it's odd that PC left Dippy's name out of her guest list. Who does that? Why would you invite one half of a couple and leave the other one out?" a source told DNA.

We wonder what could be the reason behind her actions as though Priyanka and Deepika are considered to be arch rivals, they have always maintained that they are cordial with each other.

Meanwhile, Nick' parents -- mother Denise and father Kevin Jonas Sr -- who flew down from the US with their son to Mumbai for the traditional Indian pre-wedding ceremony, also attended the party with Priyanka's mother Madhu Chopra and brother Siddharth at the actress' residence. They were seen dressed in Indian wear for the celebrations.

Priyanka's cousin Parineeti Chopra and Siddharth Roy Kapur, producer of Priyanka's new film "The Sky is Pink", were among the first guests to arrive at the party.

Alia Bhatt, Anusha Dandekar, Mukesh Ambani, Nita Ambani and Isha Ambani also came to congratulate the couple, as did directors Vishal Bhardwaj, Sanjay Leela Bhansali and Siddharth Anand.

Salman Khan's sister Arpita Khan Sharma attended the party along with her husband Aayush Sharma and writer Mushtaq Sheikh.

Popular DJ Khushi played the music as the guests enjoyed the night. In some videos shared on social media, Priyanka, 36, is seen dancing away while Nick, 25, is seen shaking his head like a bobblehead.

A family picture also sees Nick and Priyanka kissing the former's parents on the cheek.

"What an amazing day of celebration for @nickjonas and @priyankachopra engagement and Indian culture," Nick's father Kevin Jonas Sr posted on Instagram.

This celebration followed a 'puja' earlier on Saturday, after which, Priyanka announced to the world, "Taken... With all my heart and soul", on Instagram with an intimate photograph with Nick.

Nick introduced her as the "Future Mrs Jonas", though the couple hasn't announced their official wedding date yet.

Friends and family members are happy for the couple.

Nick's brother Joe Jonas tweeted: "I couldn't be happier for my brother. Welcome to the family Priyanka Chopra. We love you."

Kevin Jonas also congratulated the couple via an Instagram Story, but the Jonas patriarch wrote: "So happy for the engagement of our son Nick Jonas and we welcome Priyanka Chopra into our family with love and excitement."

"Game of Thrones" star Sophie Turner, who got engaged to Joe last year, wrote: "Wow. First I'm blessed with an incredible future brother-in-law, and now such a beautiful, inside and out, future sister-in-law. I'm so excited to welcome you into the family (Priyanka Chopra). I love you both."

Priyanka's family members and friends are convinced she has found her perfect partner.

"I can't think of a more a perfect man for her," Parineeti posted on Instagram, urging Nick to love her "Mimi didi" because "she loves you like mad".

"Protect her, because shes strong, but a soft soul inside. I love you both and wish you all the happiness forever," she added.

Anusha Dandekar, who is a close friend to Priyanka, said the couple makes "love look so easy, beautiful and special".
