Jolie - who has Maddox, 19, Pax, 17, Zahara, 16, Shiloh, 14, and twins Knox and Vivienne, 12, with ex-husband Brad Pitt - recently joked she's been single "for a long time" because she's so picky about her partners.
Asked if she has a list of "nos" when it comes to finding a new guy to date, she quipped: "I probably have a very long list [of 'nos']. I've been alone for a long time now."
Last month, it appeared she'd got back in touch with her ex-husband Jonny Lee Miller, whom she was married to between 1996 and 1999.
An insider said: "On her first evening with Jonny, Angelina only took Knox along, and they got on like a house on fire. Knox is a sweet kid, and I imagine she decided he was the easiest one to begin introductions with."
The source also claimed she returned to Miller's apartment with Pax the following day so that he could get to know the "Elementary" actor better.
They added: "They only hung out for a short while at Jonny's apartment, but they seemed to get along well."
Jolie was said to have been keen to introduce Pax to the "Trainspotting" actor because the teenager is thinking about attending college in New York, where Miller lives.
