Jennifer Aniston 'offers' key help to Selena Gomez

In the run-up to Selena Gomez's wedding, sources say Jennifer Aniston - her close friend - offered her to give a key set of advice on her marriage.

Insiders say this is because the Friends actress has planned several of her friends' weddings before, so her experience would come in handy for the Grammy-nominated singer, with whom she first met in a bathroom at a Vanity Fair event.

"Jennifer treats Selena like a younger sister. She's very excited for her and has already sent flowers and a card offering to help out however she can," the tipster tattled to In Touch.

"She's planned a couple of weddings herself, so she knows a whole lot about the process and has a lot of advice to share. No doubt Selena will be happy to have her guidance."

"It's hard enough planning a wedding, but a celebrity one is on a different level so any help she can get will be appreciated," the mole squealed.

On the other hand, the pair's wedding is said to be a 'celebrity gala' as the couple have many A-lister friends in the industry. 

Last December, Selena shared a snap of herself with Benny and a photo of her ring announcing her engagement on social media.
