Jennifer Aniston hosted a star-studded birthday party for fiance Justin Theroux on Saturday.

The bash was rumored to be their secret wedding — you know, the one she has incessantly insisted, while doing media rounds for “We’re the Millers,” that they didn’t have time to plan?

But alas, the event was not the couple’s walk down the aisle.

Instead, the “Friends” alum hosted about 80 guests at her newly renovated Bel-Air abode, which she purchased in February 2012 for $24.9 million and spent quite a bit of time renovating, for her actor beau’s birthday, just like her rep said she was doing.

Those wedding rumors perked up again when no-parking signs were put up around the house over the weekend and a large shipment of Champagne was delivered Friday. Aniston also invited her hairstylist Chris McMillan to her house to style her coif.

The timing was also perfect, since the day marked the one-year anniversary of Theroux’s proposal to the actress. He proposed on his birthday last year, so the rumor mill had that occasion-eclipsing precedent to go on.

Maybe this was her way of saying, “Hey, thanks for proposing to me on your big day last year, allow me to return the favor.”

The casual affair mostly took place on Aniston’s massive patio and manicured grounds around her pool, Radar Online reported. Theroux and many of the guests reportedly wore jeans.

“Justin looked very happy and like he was really enjoying his birthday and showing off their new house,” as source told E!.

Partygoers included Ellen DeGeneres and wife Portia de Rossi, Kristen Bell and fiance Dax Shepherd, Tobey Maguire, Isla Fisher and husband Sacha Baron Cohen, Don Cheadle, Jimmy Kimmel, Tobey Maguire and his wife, Jen, Ben Stiller, Jason Bateman and Lake Bell, according to a few reports.

Other guests surrounded a fire pit inside the living room, near a huge bar, and an indoor-outdoor deck was home to a buffet of finger foods and small appetizers prepared by Aniston’s personal chefs, E! reported. The affair wrapped up around 11 p.m.

Happy birthday (not congratulations), Justin!
