Convicted ex-state Sen. John Sampson was too “embarrassed” to admit he’d been suspended from practicing law when he was caught wrongfully appearing on a Family Court case, ­according to court papers.

The admission was made by the disgraced Democrat related to his Brooklyn federal court sentencing next month in a fraud scheme.

In March, Sampson appeared in Brooklyn Family Court with one of his clients — although he was suspended from practicing following the conviction.

He withdrew from the case, but didn’t mention the suspension “due to my great embarrassment,” he wrote.
