Lovebirds Ashton Kutcher and Mila Kunis went public with their romance at a Los Angeles Lakers basketball game on Friday night (03Jan14) when they kissed for the cameras.

The courtside couple was all smiles as the Staples Center's famous Kiss Cam turned on them, and they locked lips as fans cheered.

Kutcher attempted to keep the kiss private by shielding his smooch with his Lakers baseball hat, but the fact the two former That 70s Show co-stars are an item has been common knowledge for months.

And a month ago (Dec13), Kutcher posted a photo of him kissing Kunis during a trip to Sun Records in Memphis, Tennessee.

Kutcher finalised his divorce from Demi Moore in November (13).

The couple wasn't the only loved-up pair at the Lakers game on Friday night - newlyweds Kaley Cuoco and Ryan Sweeting were also spotted courtside.

The pair wed on New Year's Eve (31Dec13).
