If you wannabe a real Spice Girls fan, you gotta tune into this Sunday's episode of "Oprah: Where Are They Now?" to get the lowdown on what  Mel B. (AKA “Scary Spice”) has been up to lately.

We have an exclusive clip (top of the page) of the Spice Girl and "America’s Got Talent" judge talking about how she balances her career with being a mother of four girls, one of whom we see is an adorable mini-me version of Mel B.

She says she's a "strict mum, but I have a lot of fun." She'll also discuss the possibility of a Spice Girls reunion on the episode. 

Sunday's airing also includes a sit-down with legendary new age composer Yanni, who takes a break from preparing for backstage a Royal Albert Hall gig to talk about the key to his success and his failed marriage to "Dynasty" star Linda Evans. 

Two more veteran "Oprah" guests will be interviewed, including the 9/11 widow whose grief-fueled shopping addiction added up to $5 million and caused an outrage.

The episode airs this Sunday, July 13 at 9:00 p.m. ET/PT on OWN.
