Singer August Alsina insists he gave former lover Jada Pinkett Smith "advanced notice" that he was going public with the salacious details of their alleged love affair.

The musician hit headlines last week after claiming he was involved in a torrid secret romance with Jada for years -- and he even received the blessing of the actress' husband of 23 years, Will Smith.

Alsina, 27, defended his decision to go public. He explained in an Instagram post on Friday, July 3, that he needed to share the truth to free himself from "oppression" and "the invisible walls of silent societal construct".

In the lengthy note, the "No Love" singer argues the backlash to his comments only serves to fuel his search to be his true self and "reach the gift of harmony within myself".

He goes on to insist he didn't betray anyone's trust, as he gave the Smiths advance notice of his candid interview with New York radio personality Angela Yee.

"My heart has no malice or hate toward anyone on this planet," he states. "I just simply want the chains off & I'm willing to DIE getting there. The gift of freedom is yours to have, God promises us that, but only if you're willing...

"i should also say that, no one was side swiped by any conversation, everyone got courtesy calls time in advance. Wishing Everyone Big Love!"

The Girls Trip star's rep dismissed the allegations as "absolutely not true", but Jada, 48, subsequently teased an upcoming tell-all episode of her Red Table Talk Facebook series.
