Fans all over Twitter are wondering why Robin Roberts has not appeared on "Good Morning America" this week.

Roberts announced on April 4 that she will be taking a brief sabbatical.

Fans who missed the tweet have been blowing up co-host Lara Spencer's Twitter account, asking "Where is Robin?" Spencer responded to several GMA viewers, telling them that Robert will be back on Monday, April 14.

It appears Roberts is taking time to relax outdoors, tweeting a magnificent view while plugging her new book, "Everybody's Got Something," which will be released in two weeks.

Roberts has also been tweeting about the NCAA basketball tournament, appearing on the cover of Good Housekeeping Magazine, and her upcoming appearance at the Tribeca Film Festival.

She also reassured her 700,000 followers that there was nothing to worry about by sending a tweet on Wednesday.

With all of the shake-ups at GMA, fans had a reason to worry.

Co-anchor Josh Elliott, who had been with the show since 2011, quit the program last week via e-mail to join rival station NBC. In January, weather anchor Sam Champion also left GMA to join NBC. There are also rumors that Lara Spencer and Amy Robach are feuding, and that George Stephanopoulos is unhappy at the show. 

Another change at the ABC morning show is the addition of "Live! with Kelly and Michael" star Michael Strahan. He will join the show on a part-time basis, although it is unknown when his start date is. Strahan will join GMA anchors Amy Robach, Robin Roberts, Lara Spencer, George Stephanopoulos and Ginger Zee.
