The Saturdays star Una Healy kicked off her bachelorette weekend (25-27May12) with a raucous night out in London on Friday.

The British pop singer and her rugby player fiance Ben Foden, who are parents to two-month-old Aoife Belle, are set to exchange vows next month (Jun12), and Healy marked her last few weeks as an unmarried woman by enjoying a spa day on Friday afternoon.

But the pampering session was just a warm-up for Healy, who headed out in the U.K. capital with a big group of female friends in the evening.

She was snapped wearing a frilly red garter under her short cream dress, with a veil and tiara on her head as she partied at London's Brompton Club.

Healy is also preparing to enjoy a joint bachelorette party with her The Saturdays co-star Rochelle Wiseman on Saturday night (26May12) - and their bandmate Vanessa White is looking forward to the celebration.

In a post on her Twitter.com page, she writes, "Yeah yeah, its (sic) finally here HEN DO! Right girls let's show these boys how its (sic) really done!"
