Most of the actors and actresses do not use the original names and if at all they use they will change their names as per the advice of astrologist or numerologist. Falling on these lines, Poonam Kaur has also changed her name as Nakshatra.

Poonam Kaur made her debut as heroine in the Tamil film Nenju Irrukkum Varai. After this she was not seen in Tamil films. Since she did not get offers as expected she switched over to Telugu films.

There she had acted in few films. At this point of time, she made her reentry in Tamil film through the film Payanam produced by Prakash Raj. Since someone told her that this film is doing well and it is appropriate time to change her name, she consulted a few numerologists and astrologers and changed her name as Nakshatra.
Poonam Kaur says this name is lucky because she immediately got the opportunity to act in a film to be directed by Prabhu Deva which has Vishal in the lead role.
