(Yahoo!) - Ciara is planning a future with Future.

The R&B singer became engaged to rapper-producer Future over the weekend, a publicist for the couple told the Associated Press.

The "Body Party" songstress, who turned 28 on Friday, was celebrating her birthday in New York with her beau, 29, surprised her with a 15-carat diamond. No wedding date has been set.

She tweeted:

The couple, who has been dating for a year, has made a string of appearances together on the red carpet in 2013, including the MTV VMAs, BET Awards, and Clive Davis's pre-Grammy gala. In April, things between them looked serious when they debuted matching ring tattoos on that finger. Hers is an "N" (his real name is Nayvadius Cash); his is a "C" (her full name is Ciara Princess Harris).
