Madison Beer and Justin Herbert shared a lightning quick interaction at the Los Angeles Chargers game Sunday ... sharing a kiss on the sideline before the game!
The pop star stood just off the field at SoFi Stadium Sunday ... hanging with a pair of friends when her footballin' BF came over to say hello.
Like we said, it's short and sweet ... Herbo plants a kiss on Beer's lips and shakes her friends' hands before kissing Beer again and jogging off.
