Jennifer Aniston is said to have shown "no indication she is upset" following her split from Justin Theroux.

The couple confirmed yesterday, they separated at the end of last year after two-and-a-half years of marriage, and the 49-year-old actress is said to have shown "no indication she is upset".

A source said: "Jen and Justin have been apart for several weeks. Jen has continued her life as usual.

"She has seemed fine. There has been no indication that she is upset."

The former 'Friends' star is said to have been spending time with pals following their break up, and she will stay friends with Justin, 46. 

The source added to PEOPLE: "[She] has spent time with friends, like she always does.

"She and Justin started out as friends, and always admired each other a lot. It seems they will continue to be friends."

The former couple - who married in August 2015 - confirmed they had separated in a joint statement, admitting they will continue to have a "cherished friendship" and are keen to "maintain the love" they have for one another. 

They said: "In an effort to reduce any further speculation, we have decided to announce our separation. This decision was mutual and lovingly made at the end of last year. We are two best friends who have decided to part ways as a couple, but look forward to continuing our cherished friendship.

"Normally we would do this privately, but given that the gossip industry cannot resist an opportunity to speculate and invent, we wanted to convey the truth directly. Whatever else is printed about us that is not directly from us, is someone else's fictional narrative. Above all, we are determined to maintain the deep respect and love that we have for one another."

Jennifer was married to Brad Pitt from 2000 to 2005, and the 54-year-old star is currently going through a divorce with Angelina Jolie, who he tied the knot to in 2014.
