The 32-year-old, who is said to be dating manager Tim Witherspoon, recently flashed a huge rock while wishing songwriter-producer friend Patrick "J. Que" Smith's child a happy birthday via Instagram, reports eonline.com.
When she raised her left hand to blow a kiss to the child, one could spot a diamond ring on her wedding finger.
Rowland's representatives have remained silent and refused to confirm anything related to "The X Factor" judge's engagement.
The singer earlier said that she was "too busy" to consider getting married soon.
