The Blurred Lines artist began dating Geary back in September of 2014, a month before Patton filed for divorce (they separated that February), alleging he committed infidelity, abuse and drug use.

She celebrated their latest anniversary on Instagram, writing: ‘6 YEARS. Omg SIX years, two babies, one burned down house and one less appendix between us. I love you so much and I couldn’t imagine my life without you. 

‘You’re the best father, partner, cook, lover! I know I’m rarely ever romantic or serious (lol) but you’re truly my other half and you love me more than anyone ever has before. Forever & always.’

The couple lost their Malibu home in the Woolsey Fire in November of 2018, which she revealed on Instagram.

Geary posted a photo of the clouds of smoke, writing: ‘Our house is somewhere in there. I’m so sad but so thankful that we all made it out safe. Praying for everyone in Malibu, our city is up in flames.’
