Nadine Coyle is expected to announce her engagement to Jesse Metcalfe soon according to DigitalSpy.
Nadine has been supporting the 'Desperate Housewives' actor while he is in rehab to battle an alcohol problem, and friends believe that they have now been brought closer together.
A friend of the Girls Aloud singer told the Daily Star Sunday, "It's been really tough on Nadine but thankfully everything seems great now. She was absolutely gutted to be begin with but she recognised that Jesse needed help. And fair play to Jesse, he took that first hard step of going into rehab."
"Nadine has been there for him ever since. They've been on the phone every day for the past week. And now you can hardly get them off it! Jesse is much, much cheerier and because Nadine's such a positive person she's really helped to lift him."
"They'd talked about getting married a couple of months ago and everyone is expecting an announcement pretty soon. Jesse should be out shortly - and Nadine will be there waiting."
