Must be chilly! Ariel Winter puts on a cheeky display in booty shorts despite plunging temperatures in LA

Temperatures dropped in Los Angeles over the weekend. 

But Ariel Winter was still in summer mode on Saturday as she donned a tiny pair of shorts for an outing at the Westfield Century City mall.

The 18-year-old actress was joined by a gal pal and looked laid-back on her weekend outing as she put on a cheeky display in the pair of itty-bitty shorts while making a caffeine pit stop at The Coffee Bean & Tea Leaf.

Ariel bared her booty and showed off her athletic toned and tan legs in a pair of tie-dye short shorts. 

She teamed her eye-catching look with a simple white T-shirt and layered a large faded denim jacket on top concealing her new tattoo but not her uncovered bum.

The petite five-foot-one star went for ultimate comfort going sans make-up and adding a pair of stark white trainers to her off-duty look. 

The actress also toted a pricey Celine luggage tote - which retails for roughly $3,000 - around her arm. 

The raven-haired beauty left her shoulder-length tresses down and straight.

Ariel's gal pal minicked her famous friend's casual style as she also wore white trainers and a similar style coat which she teamed with grey leggings.

Ariel appeared in high spirits and like she was enjoying her company although she remained glued to her cell phone in her hand.  

The same day the actress enjoyed some pampering and self care as she revealed a fresh manicure on social media. 

Ariel posted a picture of her long white nails and included a caption thanking her Beverly Hills nail salon. 

Meanwhile, the starlet recently added to her collection of body ink with a new tattoo of a spade on her wrist. 

New episodes of Ariel's ABC smash hit comedy Modern Family air Wednesdays at 9pm.
