The couple puckered up for the crowd after being caught on KissCam while watching the LA Lakers on Tuesday night (27 January).
Cameron, 42, and Benji, 35, have just returned to California from their honeymoon, which is believed to have been in Jackson Hole, Wyoming.
According to Us Weekly, the superstar pair - who prefer to avoid the spotlight - wanted a low-key celebration following their nuptials and chose a rustic and rural location.
Actress Cameron and Good Charlotte rocker Benji married at a secret ceremony at their Los Angeles home on Monday, 5 March, attended by friends and family including Drew Barrymore, Benij's twin brother Joel Madden, and Joel's wife Nicole Richie.
In a statement, the happy couple said they "couldn't be happier" to start married life together "surrounded by our closest family and friends."
Cameron and Benji had never officially confirmed their engagement ahead of the nuptials, but rumours had been swirling last year after Cam was seen wearing a diamond ring.
