Britney Spears and K-Fed -- Well This is Awkward

Britney Spears and K-Fed ... Well This is Awkward

Britney Spears and Kevin Federline cheered on their son during a soccer game today ... alongside Brit's new boyfriend.

The trio came together in Tarzana today for an awkward -- yet respectable -- moment ... and didn't seem too fazed standing side by side ... by side.

Makes sense ... since K-Fed made it clear to us last month he had moved on with his life and didn't really care about things going on with Britney anymore.

Stronger.
