The 31-year-old was reportedly asked by producers of the hit reality TV show to appear alongside her aunts, Kyle and Kim Richards, reported Radar online.
"Paris was asked to be a part of the finale which will take place in mid-July. She is a big fan of the show and totally supports her family appearing on it, but had to decline because she will be out of the country. Paris will be extremely busy promoting her new album, and just has too much going on right now to commit to taking on anymore projects," a source said.
