Amber Rose has hinted she has tied the knot with Wiz Khalifa.

The 29-year-old model - who is expecting a baby boy with her 'Black and Yellow' rapper fiance - has sparked speculation they are already married after referring to him as her husband.

When given a Ninja Turtles ice-cream bar, she told gossip website on Tuesday (15.01.13), she said: ''My husband loves Ninja Turtles.''

Wiz previously revealed that the couple planned to marry legally in court before their baby arrives but would throw a big traditional bash afterwards so that the model could enjoy the day.

He said: ''When you have the ceremony, that's when you invite the family, she can fit into the dress, and if we have a daughter one day she might want to give the dress to her daughter, but if she's pregnant she can't do that.''

The couple recently celebrated the upcoming arrival of her first child with a no frills blue-themed baby shower with family and friends.

Amber shared details of her party with her Twitter followers, writing: ''We had a good ol down home baby shower today. No papz, no booshiness just fun, friends, family, food and good times. (sic)''
