She apparently spoke out at an awards ceremony about her friendship with the more established Bollywood actress.
A source told DNA India: "Usually, whenever two actors share screen space, there are numerous reports talking about the rift between them. It was the same with Kangana and Sameera too.
"A lot has been spoken about their supposed cold war, but Sameera's statement seem to say otherwise. She didn't hesitate even for a second to praise and support Kangana."
The insider added: "Sameera had claimed that they go away a long way; insisting that they formed a bond way back when Kangana was just getting into the industry.
"She even said that she even helped Kangana with her dance skills, as she is a trained dancer herself."
In March 2011, Ranaut said that she had to make it "on her own" in Bollywood because she had no famous family members.
The Tanu Weds Manu star fell out with the Dutt family last year because of comments she made distancing herself from them.
