Justin Theroux's Birthday Party Was A Star-Studded Affair

Being two of the most beloved celebrities in Hollywood, it's no wonder A-list guests flocked to Jennifer Aniston and Justin Theroux's Bel Air mansion for a intimate gathering last night (Aug. 10).

Aniston threw her fiance Justin Theroux a star-studded 42nd birthday party at their newly renovated home exactly one year after the pair got engaged.

According Us Weekly and People, the 44-year-old actress and her man entertained guests including Laura Dern, Lake Bell, John Krasinski, Will Arnett and celebrity couples like Ellen DeGeneres and Portia de Rossi, Tobey Maguire and Jennifer Meyer, Dax Shepard and Kristen Bell, Jimmy Kimmel and Molly McNearney and Jason Bateman and his wife Amanda Anka.

Although reports surfaced that Aniston and Theroux were set to exchange vows during the bash, it appears that Theroux's birthday was the only celebration last night.

"It's a birthday," Theroux's rep insisted to E! News yesterday. "Not a wedding. Today is Justin's birthday."
