Jennifer Lopez has returned to the LA gym which she was locked out of on Wednesday – as the somber star was seen getting back to her fitness regime.

The star, 53, found herself locked out of  Tracey Anderson’s luxury fitness studio  after she rolled up in a SUV for a workout sessio

When she emerged after the class some time later, she appeared to be in a rather cranky mood and even dropped an F-bomb while making her swift exit.

The star flashed her abs in a cropped tee emblazoned with a graphic of singer Selena – who she played in the 1997 film, paired with pink joggers as she stepped out on Thursday.

She wore her highlighted tresses in a casual updo and sported a radiant palette of make-up.
