This year, actors like Sunny Deol, Urmila Matondkar, Shatrughan Sinha and Prakash Raj among others contested polls.
While Sunny, a BJP candidate from Gurdaspur is leading by over 77,000 votes, Urmila is trailing against BJP's Gopal Shetty in Mumbai North.
Dharmendra took to Twitter to congratulate both his son and PM Narendra Modi with a picture of the two.
"Faqeer Badshah Modi Ji, Dharti puttra Sunny Deol, Congratulations. Achhe Din Yaqeenan Ayen ge (Dervish-king Modi ji, son of soil Sunny Deol, Congratulations. Good days will definitely arrive)" the veteran actor captioned the post.
Dharmendra also congratulated his wife, actor Hema Malini, who is contesting from a BJP ticket from Mathura for a second time in a row. She is currently leading with over 284,000 votes.
"Hema, Congratulations. We love Mother India, we have proved in Bikaner and Mathura. We will keep our (national flag) flying. Always," he said referencing to his own win from Bikaner in 2004.
Malini, on her part, credited Modi for BJP's win.
"What a clean sweep!The opposition & the Congress silenced totally! Modiji, after having suffered so many insults, many personal, stands totally vindicated as a true nationalist in whom the masses have reposed complete faith & view as a leader who can make India excel in all spheres," the actor tweeted.
Producer Ekta Kapoor posted a picture on Instagram with her son Ravie sitting in front of the TV, watching the results for Amethi, where her long-time friend and former actor Smriti Irani is contesting against Congress president Rahul Gandhi.
"All eyes on Amethi, we are rooting for our aunt," she captioned.
Actor Riteish Deshmukh took to Twitter and wrote, "India has decided - Democracy needs to be celebrated. Many Congratulations to our Hon Prime Minister Narendra Modi ji on this huge verdict."
Filmmaker Shekhar Kapur in a tweet wondered why the world does not want to believe the Indian Voter has a mind of its own.
"The rubbish I have been reading makes them look like sheep following a herd. 85 million are first time voters who voted for a better future. The results will declare who they believe will give it to them," he tweeted.
Filmmaker Hansal Mehta wrote that it is time for "many of us to understand the changed narrative of our times".
"People have voted and their vote is for a firm and stable government at the centre. Was there any need for the violent, vitriolic and personal campaign run by parties, leaders and media?"
On a lighter note, the election also saw actor Sunny Leone trend on Twitter after a leading TV anchor slipped up during his election broadcast, mistakenly saying Sunny Leone instead of Sunny Deol .
The joke was not lost on Leone, who joined the meme-fest with her own tongue-in-cheek remark.
"Leading by How many votes?" she tweeted with a wink emoji.
Amid the congratulatory messages, there were some who could not help but take a pot shot at the condition of the opposition in India.
"BJP ki vishaal jeet ke liye saare Vipaksh ko badhaaiyaan. Aap sab ke sehyog ke bina ye jeet lagbhag namumkin thi. (Congratulations to the Opposition for the great victory of BJP. This win was nearly impossible without your support)," said actor Deepak Dobriyal.
