The striker, who previously hit out at the club after a blocked move to Tottenham, has apologised for his actions, stating he has a good bond with Tony Pulis and Jeremy Peace
The 22-year-old was denied a move to Tottenham at the start of the campaign and lashed out on social media, claiming he would never play for chairman Jeremy Peace again.
Berahino has only started nine Premier League games this season having struggled for full fitness, while he was also dropped by boss Tony Pulis due to an undisclosed incident.
He then remained silent during the January transfer window, when Newcastle United had a £21 million bid turned down by West Brom.
But Berahino has now apologised to both West Brom and the club's fans for his actions, claiming his relationship with Peace and Pulis has always been strong.
"It is something that I look back on and really regret," he told the club's Youtube channel when asked about his outburst against Peace.
"I should never have said that. We all make mistakes and I hold my hands up and say it was a mistake from me.

"I just apologise to all the fans out there that have always supported me and also the club who have always believed in me.
"I don't really want to get back into and look into the past. I'm in a good place right now, we're all in a good place. I get on really well with the chairman so there's no problem there.
"I have always got on with the chairman, I have never had a problem with him."
When asked about head coach Pulis, Berahino added: "We have always had a good relationship. I have never had a problem with any of the managers I have worked with really.
"I can't say I have ever had a problem with him and I don't think he would say I have had a problem with him. We get on well and I'm just glad he is helping me getting through this tough time I have had in the past.
"I have always been hungry. I couldn't control certain things that happened in the past but we are all humans and we make mistakes. I am just focusing on getting back to my old self.
"A lot of things have happened and I don’t think people know the full ins and outs, but I can't look back at the past anymore."
