Happy news: Pregnant singer Una Healy last night announced she was engaged after boyfriend Ben Foden asked her to marry him
It's been an incredibly busy year for Una Healy.
As well as The Saturdays achieving huge success with their new album and arena tour, the 30-year-old singer announced she is expecting her first child with boyfriend Ben Foden.
And now the stunning singer has rounded off 2011 by getting engaged to her rugby playing beau.
Una announced the happy news during The Saturdays' performance at London's Wembley Arena last night after Ben popped the question.
She proudly showed off her new engagement ring as she excitedly bounded around the stage with her bandmates.

After telling fans her news, Una wrote on her Twitter page: 'Thank you WEMBLEY!!
'Such an incredible night, so happy right now, :) xxx'
The 26-year-old sportsman had made no secret of his desire to ask Una to marry him, saying earlier this year he was just waiting for the right moment.
He said: 'I am planning to go down on one knee during the next few weeks. It won't come as a total surprise because we've been discussing marriage for some time.

'It will happen and I want lots of children.'
Ben also said that he had already chosen the type of ring he was going to use to ask Una.
He said: 'I plan to do it right with a simple, classic item from Cartier so she won't refuse me.

'But Una is very discerning about jewellery. I've bought her a couple of pieces but she didn't like them. I guess they were too fussy!'
Una and Ben revealed earlier this year that they are having a little girl.
She said: ' 'I come from a family of girls, I went to an all-girls school and I'm in a girl band, so I guess it's fitting that I'm having a daughter.'
Ben added: 'We weren't trying for a baby. But we'd talked about starting a family and we're in a loving and committed relationship, so it wasn't a massive shock.

Una has been touring the UK with The Saturdays on their All Fired Up tour, and the girls all tweeted their excitement about headlining Wembley.
Rochelle said: 'That was the best thing that's EVER happening to me, headlining Wembley!
'Happy happy girl wow! It hasn't sunk in yet! I'm so blessed x'
