Something wrong Michelle?

She's got a plum role on Britain's most loved soap, but by the glum look on Michelle Keegan's usually smiling face, it seems even actresses can get the back to work blues.
Wrapped up in a warm coat as she strolled around the Coronation Street set in Manchester, the 25 year old looked decidedly glum as she returned to work after tweeting that she 'had the best weekend!!! ☺ X'

Luckily for Michelle, there's plenty of interesting scenes to film ahead as her character, Tina McIntyre, enters the final stages of her surrogate pregnancy.

Downcast on the cobbles: Michelle Keegan can't raise a smile on the set of Corrie in Manchester

Though she didn't say exactly what it was that made her weekend so special, there's a good chance her boyfriend Mark Wright had something to do with it.

The couple, who have been dating since late last year, are so smitten,  family and friends are speculating that it's only a matter of time before they walk down the aisle.
But only weeks ago, the pair were thought to be on the rocks thanks to a Twitter conversation in which Michelle seemed annoyed at her boyfriend for wanting to extend his holiday in Austria.

Mark tweeted: 'It's the little things in life that matter. Like the fact you can go for a Sunday stroll and just the thought of 1 person makes u smile.'

The Only Way Is Essex star says Mark and Michelle are 'best friends' and said that their joking tone just didn't come across well on Twitter.
Jessica has made no secret of her fondness for Michelle, calling her 'an absolute angel' and raving about how down-to-earth she is.
The reality star even admitted that she is hoping the pair become husband and wife within the next two years.
Comparing their relationship to her own romance with TOWIE co-star Ricky Rayment, Jessica said: 'Ricky and I are best friends and we have a laugh together. Mark and Michelle seem to be like that as well.
'They’re very much in love. I’m happy for him.'

Indeed, Mark has been quite vocal about how much he adores his actress girlfriend.
The TV star told MailOnline: 'Two years ago I was reading FHM and now my girlfriend is the best looking girl in FHM. I do really love her.'
And despite cheating on his ex, long-term girlfriend Lauren Goodger, Mark insists that he is a changed man with Michelle.
The 26 year old says: 'I think everyone knows I wasn't the best boyfriend in the world before but this time it's for real.'
