The 42-year-old, who is dad to Amelia, two, with Macdonagh and Junior, 10, and Princess eight, with former partner Katie Price, said he wants to have another baby by the end of the year.
"Ems just has to say when and I’m ready to go," Andre told OK!

"We see each other when we see each other with the kids, and it’s all nice," he explained.
"We all get on really well, which is excellent, so that just adds to the peace and the serenity, and the kids are really happy and it’s really nice."

Opening up about having a fourth child is nothing new for Andre.
During the NTAs in January 2016, Andre alluded to the fact he was ready to have another baby, but was waiting on his wife.
"I have to wait for her to say yes," Andre told OK! Online. "It might take some time."
Back in October 2015, MacDonagh, who is now a qualified doctor, explained why she was keen to wait a bit longer to have her second child.
"I really want to see how my work's going," she said. "It's quite difficult for me as I love my time with Millie and I feel we have such good one-on-one time."
Andre added: "I don't want to be 50 and changing nappies."
