The former 'Friends' actress is currently planning her nuptials with Theroux and Wilson, who is married to Tom Hanks and a close pal of Aniston, is extremely excited to watch her good friend finally tie the knot, reported Contactmusic.
"There will be dancing, there will be laughing. By the end of it all you'll have blisters on your feet and leave with a smile on your face at the crack of dawn," she said.
The couple are said to have reportedly moved their wedding dating in order to not clash with Aniston's ex-husband Brad Pitt's nuptials to Angelina Jolie.
"She does not want her day associated with them. Justin got weirded out by all the rushing ... Nothing has happened on that front (wedding) in a month," a source said.
