Amanda Bynes announces engagement and shows off massive diamond ring

Amanda Bynes shocked fans over the weekend by announcing that she is engaged.

On Valentine's Day, the 33-year-old quietly uploaded a photo of her sporting a massive rock on her ring finger with the sweet caption, "Engaged to tha love of my life." Fans and friends were quick to congratulate the former Nickelodeon star, but also begged her to spill the details about her mystery man.

While the former actress chose to keep his name quiet, Bynes posted a selfie of her standing next to her future husband -- only identifying him as "Lover."

She also treated fans to another romantic selfie on Monday of the two snuggling together on the couch. This time, the photo remained without a caption and the comments were turned off.

E! News did some digging and confirmed Bynes' fiance's identity -- a man in his 20s named Paul Michael.

E! reports that the two have been dating for about two to three months and met while Bynes was in rehab.

The former actress has since left rehab and is now living in a sober living house. Bynes also revealed on Dec. 30 that she got a new tattoo -- a small heart underneath her left eye.
