Did you forget your top? Ashley Greene gets it wrong as she flashes her bra under a pair of dungarees out in LA

Ashley Greene appeared to have forgotten an essential item of her wardrobe on Saturday.

As she picked up her dog from Glendora, California, the 26-year-old Twilight actress flashed her white bra under a pair of short dungarees.

Either not realising that she needed to wear a top as well - or wanting to make a daring fashion statement - Greene put her underwear on full display for all to see.

The actress, who plays vampire Alice Cullen in the cult series, didn't seem to care that her sturdy white and lace lingerie was showing under the patterned £48 Motel Ditsy Daisy Dungarees - £48 jumpsuit while she strutted across the car park with her dog carrier on her arm.

Ashley had gone to meet two female friends for a meal at the popular chain restaurant, Chili's, before she went to get one, or all, of her dogs.

After her Fox Terrier, Marlo, tragically died in a fire at her West Hollywood apartment in March, the animal lover adopted two more dogs in June to keep her surviving pup, Theo, company.

'Today felt like a great day to rescue a puppy... Or two! I couldn't take a brother without his sister!' she tweeted, when she introduced white terriers, Rosie and Ralph, to her 2,300,000 Twitter followers.

The newcomers have already taken over the household, with their mother messaging the next day: 'Ralph and Rosie took Theo's bed, Theo took my bed, and I'm sleepy!'

Firefighters  who attended the devastation at Greene's home after the incident determined that a candle was responsible for starting the blaze that affected the seven-story apartment complex.

When she's not suffering fashion mishaps or playing with her puppies, Ashley will soon be back to work on Zack Braff's new comedy drama, Wish I Was Here.

She has officially replaced Anna Kendrick in the role of Janine - a young woman who Braff's brother, played by Josh Gad, becomes smitten with - after the Up In The Air star had to drop out because of scheduling conflicts.

The follow up to Garden State, Wish I Was Here started filming in Los Angeles last week after the Scrubs star raised $3.1 million to fund it with a monumental Kickstarter campaign.
