Fans of Jennifer Aniston and Brad Pitt were over the moon as Brad was spotted arriving at the location of Jen's 50th birthday party.
The 55-year-old actor - who split from the former 'Friends' star in 2005 after five years of marriage - was spotted making a casual entrance into the party. He arrived alone, wearing a cap and attempted to dodge the hoards of photographers that were gathered out front.
Other guests at the party were said to include another of Brad's former flames, actress Gwyneth Paltrow, as well as Jennifer's former boyfriend John Mayer.
However, while fans were excited that there was possibility that the two former flames could be reigniting a spark, a source said: "They aren't in regular contact, beyond an occasional text back and forth to wish each other the best when there's been a new project or big event."
Jen has been single for a year after her two year marriage to actor Justin Theroux failed. She still calls both her marriages to Brad Pitt and Theroux as "successful".
She said: "I don't feel a void. I really don't.
"My marriages, they've been very successful, in personal opinion. And when they came to an end, it was a choice that was made because we chose to be happy, and sometimes happiness doesn't exist within that arrangement anymore.
"Sure, there were bumps, and not every moment felt fantastic, obviously, but at the end of it, this is our one life and I would not stay in a situation out of fear. Fear of being alone. Fear of not being able to survive. To stay in a marriage based on fear feels like you're doing your one life a disservice."
