Actress Evan Rachel Wood has shot down rumours suggesting she has reconciled with estranged husband Jamie Bell after they exchanged messages on Twitter.com to celebrate their son's first birthday. The stars announced their split in May (14), less than two years after they wed, but insisted they would remain close to co-parent their baby boy, whose name has not been released. Wood marked her son's big day on Tuesday (29Jul14) by taking to Twitter to write a heartfelt message about her kid, stating, "Today is my beautiful son's birthday. One year ago my life changed forever and the light of my life came into the world watching him grow is like having front row seats to the greatest show on earth... Happy Birthday my sweet baby." She also added, "Its the babys birthday (sic). Its my 'birth' day". The tweets prompted Bell to reach out to The Wrestler beauty online to celebrate their son's milestone, writing, "Happy birth day @evanrachelwood What a ride! Love you", to which his ex replied, "what a ride indeed! Thank u 4 helping me through it all. Love you too". The sweet exchange led some followers to believe Wood and the British actor had rekindled their romance, and it was even picked up by editors at a gossip website, who tweeted, "Evan back with husband, as she wishes son a happy birthday..." The false headline caught the actress' eye and she immediately dismissed the claims, replying, "Wait what? No. Lets not start that rumor (sic)". Wood is spending baby's first birthday away from home - she is currently shooting new film Into the Forest on location in Canada and recently revealed she was unable to take the tot with her due to a delay in obtaining his first passport.
