The 29-year-old model is currently expecting her third child with footballer husband Jamie O'Hara, so she's certainly got the qualifications when it comes to knowing what a pregnant woman wants to wear.
Danielle braved the searing heat in London this afternoon (9 July) to pose for photographers in a glamorous black dress from her range, which highlighted her bump - and her toned arms.
The star upped the wow factor with a hot pink mani, smoky eyes, a bright red lip and a voluminous updo.
Danielle was joined at the launch by a string of pregnant women, who looked glam wearing the designs that will be available through Lipstick Boutique.
Danielle had tweeted earlier in the day: "All the girls getting ready in my maternity range! Looking good so excited!!!"
"Its going to be amazing for all u glam mummies 2 be."
Danielle, who announced her pregnancy in February, has already confirmed she is expecting a boy. He'll be a younger brother for her sons Harry and Archie.
