Watch Robbie Keane tell his son he’s going to be a big brother

Irish football legend Robbie Keane is due to become a father for the second time, after announcing his wife, Claudine, is pregnant.

The announcement was made on Facebook - with a video of his first son's reaction to the news.

Six-year-old Robert Junior met the news with the mix of complete confusion and delight that most kids have when faced with this kind of news - and it's heart-warming stuff.

"Very excited to announce that Claudine is pregnant with our second child. We are all delighted," Keane wrote in a Facebook post.

"Couldn't resist sharing Robert's reaction when he found out his wish had finally came through."

So delighted to announce that Rob & I are expecting our second child. Robert's wish has finally come true. 😍👼👶 https://t.co/dptVUEUO7N
