Would you take relationship advice from Jennifer Aniston? Hell to the no? Well, regardless of what you think, America’s sweetheart has reportedly been doling out some Dear Abby-style dish to pop star Rihanna in the aftermath of Domestic Disturbia 2009.

The former Friends actress has allegedly appointed herself Rihanna’s support system as she tries to stay away from her violent ex, crooner Chris Brown, Australia’s Woman’s Day reports in its Sept. 7 issue. Blabbing tattles tell the tab that Aniston, 39, recently called the 21-year-old “Umbrella” star for a Cougar-To-Kitten chat on breaking free toxic relationships.

“Jen was totally upbeat and joking with Rihanna that she’s an expert at falling into dead-end relationships,” says a snitch. “She warned her that falling for toxic men is a vicious trap. She was adamant Rihanna should cut off Chris and warned her taking him back would turn out to be the biggest mistake of her life.”
