The actress danced throughout the night with her childhood friends on the songs of "Tanu Weds Manu" a day before the wedding, said a family member adding that the song "Kudiyan de vich phire hassdi khed di... Ni kadi sadi gali bhul ke vi aaya karo" was quite a hit and was played repeatedly.
"Kangana was here (Bhambla) for attending the family marriage. Despite her busy schedule, she spent two days with us, " her father Amardeep Ranaut told over phone from his residence.
Kangana, who reached here Tuesday, left Thursday morning for Mumbai.
"Currently she is busy shooting for Sunny Deol-starrer 'Happy New Year', " her dad said. This is Sunny and Kangana's first film together as a lead couple.
In five years, Kangana, who debuted with "Gangster - A Love Story" in 2006, has featured in hits like "Woh Lamhe", "Tanu Weds Manu" and "Fashion", which won her a national award.
