The former Friends star has been filming Squirrels To The Nuts in New York over the past week, wearing a short brown wig over her usual glossy blonde locks.
Yesterday, she was rocking a tousled version of the wig as she filmed scenes in the searing heat – and we like it!
We reckon Jen's trademark long blonde tresses are her best look, but we think she can totally pull off this casual, waved 'do as well.
Squirrels To The Nuts co-stars Jen's old Marley & Me colleague Owen Wilson and is about a married Broadway director who ends up helping a prostitute-turned-actress further her career.
Jennifer has been joined in New York by actor fiancé Justin Theroux. They were seen out and about together in Manhattan at the weekend, enjoying a screening of Sandra Bullock's new movie The Heat before heading to dinner.
According to Us Weekly, they dined alongside Justin's mother at the same restaurant in Greenvich Village where Justin proposed to Jennifer on his birthday last year.
Jen became engaged in August 2012, with a rep for Justin confirming: "Justin Theroux had an amazing birthday on Friday, receiving an extraordinary gift when his girlfriend, Jennifer Aniston, accepted his proposal of marriage."
No details on a possible wedding date have been confirmed by the couple, despite endless speculation.
