Jennifer Aniston couldn't be more thrilled to have landed a star on the Hollywood Walk of Fame ... especially since it's located right next to her friend, Oscar-winning actress Reese Witherspoon.

The 43-year-old former Friends star has been heavily promoting her latest flick Wanderlust also starring real-life love Justin Theroux.

While chatting with Conan O'Brien, Aniston joked about her star being next to Reese's ... telling the host, "We can get walked on right next to each other!”

Love this lady!
