“Selena was so excited to finally spend time with Jen,” the source told OKMagazine.com exclusively. “They really bonded and Selena has been milking her for advice over everything, including health and beauty tips, how to handle the pressures in Hollywood and even advice about boys.”

Selena’s fan girl moment happened last week when she met Jen at a party at the Chateau Marmont in Los Angeles. “I have not only been following her career as a fan since I was 8 and now get to watch her completely transform in her new movie CAKE, I have gotten to have real conversations with such a real heart, made my entire year,” she wrote on Instagram.

But Jen, who “understands the Hollywood gossip scene more than anyone,” told Selena she’s proud of her for finally shaking Justin off.

Jen “was fully aware of Selena and Justin’s toxic relationship,” the source said. “She congratulated her for having the courage to walk away, saying she’ll be a wiser and more secure person for it.” Now that’s some girl power!

Jen Aniston knows a thing or two about getting over past lovers, too. The Friends star went through a very public divorce from Brad Pitt in 2055 after 5 years of marriage after he reportedly fell in love with his current wife, Angelina Jolie.

However, Jennifer has finally moved on to bigger and better things, like her movie Cake (which is generating early Oscar buzz) and her fiancé, Justin Theroux. See Selena, life does go on!
