She didn't get married at it. So, if you were only going to click into article on that basis, this does not include any photos of her being taken up the aisle by Justin. Also, you can assume Ellen DeGeneres gave it a miss.
The Cake actress turned 46 last week and she and her fiance Justin Theroux were joined at Hollywood's Roosevelt Hotel by friends including Courteney Cox, Jimmy Kimmel, Malin Akerman, Amy Adams, Lake Bell, and Ken Marino, as well as couples Sacha Baron Cohen and Isla Fisher, John Krasinski and Emily Blunt, and Tobey Maguire and Jennifer Mayer for a celebratory shindig.
A source told E! News: "The party appeared to be over just before 1 a.m. in the morning. Jennifer and Justin left through a different entrance as the rest of the party grabbed their cars from valet."
One friend (apart from Ellen. who previously said she'd only turn up if they were planning on springing an impromptu wedding on all assembled) who couldn't make the dinner was Reese Witherspoon, but the Wild star sent an incredibly lovely/gushing message to her friend via Twitter.

It was recently revealed Jennifer and Justin - who have been engaged for over two years - are now focused on planning their wedding after agreeing terms of a pre-nuptial agreement - the always romantic necessity.
A source said: "There's been a lot of talk among friends that [the wedding] could be at their Bel Air home on May 16. They came to an agreement after Justin scaled down his demands - at one point he suggested a £1.3million 'cheating clause', but that's now off the table. Jen's fortune is considerably greater than Justin's, but if the marriage ends, she'll now only pay out £1million."
