It looks as though Chelsea Handler might indeed be Jennifer Aniston's most important guest at her upcoming wedding to Justin Theroux. The Hollywood actress was spotted enjoying her weekend dining and treating themselves to beauty treatments in Los Angeles, Calif. with the talk show host and comedian.

Jennifer Aniston, Justin Theroux Wedding: Actress Set To Tie The Knot This Summer

The two women were spotted at Hollywood hotspot Mastro's in Beverly Hills. Earlier reports indicated that Aniston would ask Handler to be her Maid of Honor after having a fallout with former Friends co-star Courteney Cox. Despite their long-standing friendship, Aniston is allegedly fed up with Cox pressuring her to get married before she ties the knot this summer.

A source tells Radar Online: "Courteney has been pushing Jen to get pregnant for years! She's given Jen non-stop baby and pregnancy advice, and Jen is sick of it. She doesn't want a friend who's a total know it all. She'd much prefer to spend her time with someone like Chelsea, who would never tell her what she should or shouldn't do."

Jennifer Aniston Is Being Pressured By Courteney Cox?

Although unconfirmed, there have been reports that indicate Aniston might finally walk down the isle on August 10, which also happens to be Theroux's 43rd birthday. The couple has supposedly settled on a "low-key" wedding with only their closest family and friends invited.

This will be Aniston's second marriage as she was previously married to Brad Pitt from 2000-2005 and the first for Theroux, who was in a 14-year relationship with ex-girlfriend, Heidi Bivens.
