Are Chris Martin & Gwyneth Paltrow Back Together? -- MAYBE! [VIDEO]

Chris Martin is either back with Gwyneth Paltrow or not ... and based on what Chris said Tuesday night both options are plausible.

Photogs wanted to know if pics of the consciously uncoupled pair on May 17 signaled a reconciliation ... and he consciously hinted it might be true.

But then he warned everyone not to jump to conclusions ... which the photogs immediately did.

Neither Chris nor Gwyneth have pulled the trigger and filed legal docs to end the marriage.
