The Transformers star, whose engagement to Brian Austin Green was called off earlier this week, was spotted dining out at the Smoke House restaurant in Studio City.
Looking casual in a vest top and flared jeans, she was obviously keen to carry on with business as usual despite the separation.

Business as usual: Actress Megan Fox goes to lunch at the Smoke House in Los Angeles yesterday
The previous day she was also seen keeping up her routine with a trip to the Coffee Bean cafe in Hollywood.
Megan and Brian mutually decided to go their separate ways after a two-year engagement, with a source saying the pair are 'still friends'.
They obviously remain on good terms - Megan was leaving Brian's home earlier that morning and then paid an afternoon visit to his six-year-old son Kassius.
The 22-year-old started dating the Beverly Hills 90210 star, 35, in 2004 and soon moved in together.

Pictured in Los Angeles over Valentine's weekend, Megan and Brian looked miserable as they headed out for lunch.
A friend of the couple told Us Weekly magazine: 'The relationship had run its course.
'It's completely amicable, and they are remaining friends... they are both focusing on their careers.'
Despite not having to deal with the messy aftermath of divorce, the couple may have to undergo painful procedures to remove tattoos of each other's names.

Caffeine fix: The Transformers actress visited her local Coffee Bean cafe
Megan has Brian's name tattooed in script between her right hip and pubic bone.
At the American GQ Man of the Year awards in November, the couple silenced rumours they had split in the summer as they spoke of their wedding plans.
Brian said: 'The ceremony will be small, Originally we were talking elopement and now we might have a few people there.'
Megan added: 'It's not going to be a big wedding. I'm not one of those girls. If it happens, it will be very low-key and quick and unplanned.
'I feel like I need to set my career and do a movie other than Transformers. Then I'll explore family.'

Trouble in paradise: Megan and Brian appeared distant as they visited a LA cafe with his son Kassius on 15 February
Last year, Megan was named FHM magazine's Sexiest Woman In The World.
The actor was clearly aware of Megan's popularity with male fans and admitted he felt unattractive next to her.
He said: 'She always looks hot. I stand next to her and it's like beauty and the beast.'
Brian has previously been engaged to his 90210 co-star Vanessa Marcil, mother of his son Kassius and also dated another 90210 co-star Tiffani-Amber Thiessen in the Nineties.
Megan will next be seen on screen in the Transformers sequel Revenge Of The Fallen this summer, while Brian is currently filming TV series Terminator: The Sarah Connor Chronicles.
