The comedian, who filed for divorce from his pop star wife Katy Perry on Friday citing 'irreconcilable differences', went to the Body doctor Interactive Fitness and Therapy studios in Belgravia accompanied by 'Florence And The Machine' singer Florence Welch, Daily Star reported.
It was 36-year-old's second visit to a therapy centre within 24 hours.
He had also visited the Focus 12 rehab centre in Bury St Edmunds, Suffolk, where he is the patron.
The former addict dropped into the recovery facility, which focuses on drug and alcohol addiction, in an attempt to lift the spirits of guests at the charity.
Brand has been magnanimous and donated more than 100,000 pounds to Focus 12 over the last two years to help fund the organization.
He credits the institute for saving his life by turning him away from his own drug addiction.
Onlookers said he spent two-and- a-half hours at the centre on Friday before making a low-key exit via a back door, looking relaxed and happy.
