The 39-year-old 'Mysterious Girl' hitmaker has only been with MacDonagh, who is 16 years his junior, for five months, but he is being encouraged by his kids Junior, seven, and five-year-old Princess Tiaamii to pop the question, reported Showbizspy.
"Pete knows it's quick, but he doesn't want to wait around any longer. It's true love and he worships Emily; he honestly believes that fate brought them together.
"He's already spoken to Emily's dad about it. He wanted to reassure him he would never stop her pursuing her medical career. He knows she's the real deal and he hopes she wants to spend her life with him, too," a source said.
Andre's first wedding to ex-wife Katie Price in 2005 was an extravagant affair - which featured a horse-drawn carriage - and he thinks MacDonagh would appreciate a more modest and traditional wedding without a celebrity guest list.
"Pete really wants to get a ring on Emily's finger and is happy to have a long engagement if that's what she wants. But the key is he doesn't want a wedding like his last one. Looking back, he realises how tacky his wedding to Katie was. He is determined this will be Emily's day - he treats her like she's a queen," the source added.
