The glamour girl was speaking on This Morning about married life when she used Andre's name instead of Reid's by mistake.
During the chat with hosts Phillip Schofield and Holly Willoughby, Price said: "Me and Pete…" She then quickly corrected herself, saying: "Me and Alex…"
The interview also saw Price explaining how much she is enjoying her relationship with Reid after tying the knot with the cage fighter in February.
She commented: "I love being married again. It's completely different. We've done the house up so there's a different feel in the house. We're looking to buy a house together, it's how it should be done."
Tonight's episode of Price's ITV2 reality show What Katie Did Next will focus on her Las Vegas nuptials, though the ceremony itself will not be broadcast.
