T.J.'s estranged wife recently released a statement following the news that she and the TV star were divorcing.
She broke her silence over T.J.'s extramarital affair via a statement through her lawyer to the Daily Mail, which spoke of the "disappointment" by her former husband's "lack of discretion, respect and sensitivity".
The former couple had been married for 12 years, the same amount of time that Amy and her ex-husband Andrew Shue had been married for.
