Jennifer Aniston is reportedly ensuring she doesn't have a hair out of place on the set of her latest film, The Baster, by hiring an umbrella handler.

The former Friends star - who is dodging Angelina whilst filming in Manhattan - has reportedly been busy making sure her close ups are flawless, with the aid of some unusual hired help.

An insider tells Bettyconfidential.com: "Jen likes to have certain hair and makeup for all of her movies, especially the romantic comedies and she looks stunning in The Baster.

"She is unbelievably tan and her hair always looks perfect. She has an umbrella handler with her at all times due to the heat wave in New York."

The insider continues: "Her spray tan would literally slide off her face in the heat if she wasn't protected.

"Everyone on set is also instructed not to tell any bystanders or paparazzi what we are filming or who is in the movie.

"We tell everyone it's just a little commercial! Most people believe it and walk away without recognizing Jen."

The Baster centres around a single mother whose best friend is harbouring a life-changing secret - he's the father.
