Wearing a bright yellow saree, Rekha entered the House when the proceedings resumed after the lunch break.
This was the first time during the ongoing Monsoon Session that Rekha, who was nominated to Rajya Sabha in 2012, attended the House.
Soon after she took her designated seat, Congress members T Subbirami Reddy and Chhaya Verma went to her and had a brief chat.
Rekha and cricketer Sachin Tendulkar have earlier faced criticism from their Rajya Sabha colleagues for their poor attendance.
