British singer Jenny Frost is a mother again after giving birth to twins on Sunday (20Jan13).

The 34-year-old former Atomic Kitten star delivered daughters Nico and Blake, her first children with Spanish husband Vicente Juan Spiteri.

Frost, who also has a five-year-old son Caspar from a previous relationship, took to her Twitter.com page on Thursday (24Jan13) to announce the happy news.

She tweeted, "Good morning, our girls are here... Blake & Nico arrived on Sunday night. They are perfect... tiny but perfect!"

Frost had been due to give birth in February (13), but admitted at the start of January (13) she was suffering agonising back pain and struggling to stand due to the strain of her growing baby bump.
