Nadine Coyle has sparked speculation that she has reunited with ex-boyfriend Jesse Metcalfe... all because she tweeted him a Good Luck message.
Jesse's new show Dallas kicked off in the US earlier this week and was met with a warm reception from audiences.
Nadine had tweeted: "Congratulations @jessemetcalfe on your new show Dallas airing tonight.
"I wish i was there to see it but the family are tuning in in LA. X."
The star is currently in the UK, and stepped out at the weekend with Girls Aloud bandmate Cheryl Cole to celebrate the launch of the latter's new single 'Call My Name'.
Today is Nadine's birthday... we wonder if Jesse got her a special something?
Another Girl Aloud, Kimberley Walsh, wrote: "Happy Birthday @NadineCoyleNow! Have a fab day!!! Xxx"
HAPPY BIRTHDAY NADINE!
