Clad in a cream coloured saree and wearing goggles, Rekha witnessed the proceedings during Question Hour even though she did not ask any question.
Seated in her seat (number 99), the film actor remained in the House only for a few minutes and later left with Congress member Renuka Chowdhury.
This is the first time she has attended the ongoing budget session. She had attended the last Winter Session once also. She was nominated to the Upper House in 2012.
Some members had also alleged that celebrities were "insulting" the House by not attending it.
Article 104 of the Constitution has penal provisions for a member's absence from either House of Parliament.
