"While on vacation this weekend, I decided to return to a recovery center," Vargas said in a statement. "As so many other recovering alcoholics know, overcoming the disease can be a long and incredibly difficult process. I feel I have let myself, my co-workers and most importantly my family down, and for that I am ashamed and sorry."

She went on to add, "I am committed to battling and addressing this debilitating disease and want to thank everyone who has offered their unwavering support during this trying time."

Thankfully, ABC still has Vargas' back. "Nothing is more important than Elizabeth's health and well-being, and we stand squarely behind her," a network spokesperson said in a statement. "Our thoughts are with Elizabeth and her family, and we look forward to having her back at ABC News when she feels ready to return."

Prior to entering rehab, Vargas spoke about addiction in a tweet on Aug. 11 when addressing the recent death of Robin Williams. "I am so sad for Robin -- and his fight with addiction. My heart goes out to his wife and kids."

In January, the journalist, who's been with ABC since 1996, talked about her struggle with alcoholism on Good Morning America. "I am an alcoholic," she told George Stephanopoulos. "The amount of energy I expended keeping that secret and keeping this problem hidden from view was exhausting. You become so isolated with the secret, so lonely because you can't tell anyone what's happening."

Many in Hollywood have spoken out about their own issues with addition. ET chatted with Jersey Shore star Mike "The Situation" Sorrentino this past July about his stint in rehab.
