The We're The Millers actress - who is the niece of Julia Roberts - was snapped running errands in the sun as she hot-footed her way around West Hollywood.
Emma, 23, kept things comfy for her day out, sporting a slightly baggy pair of blue wash jeans teamed with a striped jersey top.
The pretty blonde also donned black suede ankle boots while toting all her necessities in a leopard print bag.
But while her outfit was pretty simple, Emma went all out with her accessories by rocking a striking electric blue fedora hat.
She shielded her peepers from the LA sun with retro sunnies while showing off her only piece of jewellery - her mega-watt diamond ring!
Emma is rumoured to have become engaged to her American Horror Story co-star Evan Peters, 27, in January 2014 after dating for almost two years. The actor reportedly proposed over the holidays while the pair were in New York.
However the road to romance has not been easy for the couple. In July 2013, Emma was arrested following an alleged fight with her actor boyfriend, but the case was closed and no charges made.
In a joint statement following the arrest, the couple said: "It was an unfortunate incident and misunderstanding. Ms. Roberts was released after questioning and the couple are working together to move past it."
