We couldn't imagine ever calling Jennifer Aniston by any other name, but now that she's a married woman, could it be on the cards?
Unlike Courteney Cox's decision to go double-barrel after marrying David Arquette, Jen didn't take Brad Pitt's name for their marriage back in 2000.
And having just tied the knot with Justin Theroux weeks ago, the question of surnames has unsurprisingly come up again.
Speaking in the new issue of Vanity Fair, Jen's new husband was quick to joke about the issue – but in truth he says the pair have barely discussed it.
"I made her change both names, so she’s now Justin Theroux,” he laughed. "I don’t think it would be great if she did [change her name]. I think ‘Aniston’ is going to stick with her if she likes it or not."
In true A-list style, Jen and Justin's Los Angeles wedding was completely top secret, with guests told they were arriving for a birthday party and staff at the couple's house sworn to secrecy.
Having such mystery around the big day might have been fun for some people, but Justin says he didn't enjoy having to keep quiet.
"I wouldn’t say it was fun to plan," he told the Daily News recently. “Part of the fun of planning a wedding is telling people and we had to keep it under wraps.”
We're sure Justin managed to have some fun on the honeymoon that followed though – a week-long stay at the Four Seasons in Bora Bora, where even basic suites start at around €1,200.
Joining the newlyweds for the holiday were pals including Courteney Cox, Chelsea Handler and Jason Bateman.
"We had thought about it,” Justin said of the decision to invite friends along.
"We could just do a normal honeymoon, or we could go with some friends, keep the party going, relax, and have fun. It was really special, it was really beautiful. . . . It was a fantastic honeymoon."
