Perky: Sandra Bullock looked cheerful as she left her New York apartment today for a trip to the gym
Sandra Bullock took the bull by the horns today, so to speak, and made a concerted effort to cheer herself up with a trip to the gym.
The actress has been spotted looking a little down in the dumps in recent days in the wake of her ex-husband Jesse James planing to release a tell-all-book on their marriage.
But as she left her New York apartment this morning, the 46-year-old Oscar-winning actress had managed to raise a smile.
Grin and bare it: The actress played it casual and was carrying a pair of running trainers as she made her bright and breezy exit
Sandra played it casual in three-quarter length trousers and a black top as she headed to for a workout to release some endorphins.
Yesterday she was pictured looking glum as she went out for a stroll with her adopted son Louis.
Her downcast day out came immediately after her ex-husband Jesse James revealed the book cover of his memoir.
In the book James recalls parts of his life spanning 41 years.
He writes about everything from his tough upbringing, and struggles with addiction to success and fame.
He also touches on his failed marriages, which will no doubt refer to his ex-wife, Sandra.
Speaking to U.S magazine People, he describes what the tome will entail.

'I've lived a pretty crazy life,' he said.
'My life has been defined by many things and not just the events of the last year.
'I just wanted [the memoir] to be a good story, a page-turner and hopefully people will see it as that.'
For the the cover, the 41-year-old is seen posing in the theme of the famous American outlaw with whom he shares the same namesake.

Holding a.44 Magnum revolver, he wears a Western Style suit and bowler hat.
He said he settled on the look rather than, 'some variation of a bad prom photo, serious Thinker pose like most book jackets show.'
James, the former head of now redundant West Coast Choppers, appeared in the reality TV reality series Monster Garage and also featured in the documentary Motorcycle Mania.
But the tattoo-clad star is of course most famous for his marriage Bullock - and their bitter split.
Their relationship imploded last year just days after her Oscar win for The Blind Side when she discovered he had been having an affair with a tattoo model.
Sandra then divorced James in April 2010 after more women claimed that they had affairs with Jesse during their marriage.
The split came days before Sandra announced in April that she had proceeded with plans to adopt a baby boy born in New Orleans.
Sandra and Jesse had started the initial adoption process four years earlier.
Louis was already united the former couple in January 2010, but they did not announce the news until the Oscars in March 2010.
After the couple's split, Sandra continued the adoption of the baby as a single parent.
Jesse is now engaged to tattoo artist and reality TV star Kat Von D.
