Rachel Stevens' baby daughter looked like a ''little kitten'' when she was born.

The 35-year-old star and her husband Alex Bourne welcomed their second child Minnie into the world last month, and the brunette beauty admits she has been completely besotted ever since she laid eyes on her.

Speaking in an interview with OK! magazine, she explained: ''She was beautiful when we first saw her - she looked like a little kitten.''

The couple's three-year-old daughter Amelie has also adapted well to having a new baby sister around.

Rachel said: ''It's so gorgeous to see our two girls together. Amelie was so excited to meet her sister. We completely hate each other at night-time and in the morning love each other again!''

Alex was the first to announce that Minnie, who weighed 7lbs 7oz, had arrived ''safely'' into the world on April 1.

He tweeted at the time: ''Delighted to announce the safe arrival of our gorgeous little girl! @MsRachelStevens and baby both really well. Amelie happy and 'cited (sic)''.

The couple, who got married in 2009, later released a statement saying: ''We're so happy that baby has arrived safely.''

The former S Club 7 singer announced she was pregnant with her second child back in September and, although she was aware she was expecting a girl, she kept the baby's sex a secret from the public until her arrival.
