Lefkovitz and Johnson have two sons together with the pair sporadically sharing some shots of each other and family life on social media.
The couple posted a selfie across their respective Instagram accounts with Johnson posting the sweet caption: “One person holds it down – the other one is a clown. It rhymes so it must be true. Love you @keililefkovitz.”
Johnson also paid tribute to his wife last year with another photo of the couple and writing to his 81,000 followers: “15 years Married! 21 years together! I still can’t get enough of this person.
“She’s my muse, my fire, my therapist, my comedienne, my coach, my lion tamer, certainly my best friend, and lover.
“I’m Lucky as f***… …and so is she (let’s be honest – I’m awesome and genius and sexy and humble and s***).”
