Rachel Stevens is "so happy" for Tina Barrett.
The 38-year-old star has congratulated her former S Club 7 bandmate on the birth of her baby boy, Roman.
Speaking to BANG Showbiz at Caudwell Children's Butterfly Ball, she said: "I saw she had her baby. We're in touch on Twitter, we message each other every now and again but I haven't spoken to her for ages.
"I'm so happy for her, it's such lovely news. Roman is his name; I heard on Twitter ... I sent her a message, I'm so happy for her, it's so lovely and they're such a gorgeous couple. So, so sweet."
And Rachel - who has five-year-old Amelie and two-year-old Minnie with her husband Alex Bourne - feels she is much more fashionable nowadays than she ever was in her 'Never Had A Dream Come True' days.
She added: "God I tell you, some of the things I look back on, the odd picture I see here and there. I say, 'What on earth, what was I thinking?' I mean I thought it looked alright.
"Being a pop band in the 90s was never a good look; you're always going to have your fashion faux pas but you just do it publicly. The 90s were just brilliant, it's only when you look back on it and you're like, 'Wow'. It was an amazing time, an amazing part of pop history to be a part of."
Meanwhile, the 'Some Girls' beauty teased the possibility of another S Club 7 reunion.
She shared: "I was just saying earlier tonight - I can't believe that was a year ago, it's just gone so fast. Who knows? You never know, I mean, we had an amazing time, it was brilliant being back together and if the right thing came up again ... we're always in contact with everyone now again."
Rachel attended the Caudwell Children's Butterfly Ball fundraiser at Grosvenor House Hotel, London and was joined on the red carpet by Lindsay Lohan, Simon Webbe and All Saints.
