Russell Brand and Geri Halliwell do yoga together.

The couple - who began dating after performing at the Olympics Closing Ceremony earlier this month - have developed a ''spiritual connection'' thanks to their shared hobby and particularly enjoy practising asana, the mastery of sitting still, together.

A source told The Sun newspaper: ''Geri has said they have a spiritual connection through yoga and they practise asana together.

''Russell is known for action between the sheets but he is actually very good at just sitting still in silence.

''It is something that has acted as a Bond for he and Geri as their relationship blossoms.''

For their first date, the couple shared a romantic picnic on London's Hampstead Heath just days after they both performed at the Olympics Closing Ceremony earlier this month and onlookers revealed the pair couldn't keep their hands off each other.

A source said: ''Geri and Russell were being very open about everything, there was no attempt to hide the fact that they were on a date.

''There was lots of giggling, eye contact and touching as they sat together near a couple of trees.

''They looked like they had known each other for years - and the relationship was obviously more than just friendly.''

The couple were spotted on another date at the weekend, when they took Geri's six-year-old daughter Bluebell to London's Hampton Court Palace.

Before embarking on a relationship with Geri, Russell - whose divorce from Katy Perry was finalised last month - was dating Isabella Brewster after meeting her at a yoga class.
