Toby confirmed their romance after he was spotted on the red carpet with Stella at the premiere of the Paul Potts biopic One Chance last week.
The pair posed for pictures side by side, however they have both remained silent about their feelings towards each other - until now.
Speaking to the Mail, Toby said: "We're just enjoying each other's company. She's funny and makes me laugh, and is gorgeous with it."
Toby made his name in the 90s after landing a job presenting The Broom Cupboard for BBC1. He then went on to present Live and Kicking and The O-Zone. Toby now hosts a radio show on Heart FM.
Stella, meanwhile, appeared on the 2010 series of The Apprentice. She won the show and went on to work for Lord Alan Sugar, but later quit.
Earlier this year, Stella sued Lord Sugar, claiming her job was a 'sham' but she lost her case. She has since been pictured leaving the Job Centre after signing on for benefits.
Stella has two children from a previous relationship.
