It looks like marriage is in the future for Ciara and her boo Future. The couple are officially engaged. The rapper surprised the R&B songstress with a 15-carat diamond over the weekend.

Ciara was already celebrating her 28th birthday in New York when Future popped the question, so his gift was extra icing on an already beautiful cake. The couple's publicist revealed the news to the Associated Press Sunday (Oct. 27).

"Today Has 2 Be Like One Of The Sweetest Days Of My Life! #TheBestBirthdayEver," CiCi tweeted to her 5 million followers Sunday (Oct. 28).

No wedding date has been set.

This good news will certainly rev up the rumors that Ciara could be pregnant.

Last week, reports surfaced that the 'Body Party' singer was expecting Future’s baby. Concert photos show Ciara sporting a stomach bulge through her black leather top.

Ciara and Future, who have been dating for a year, have remained quiet about the pregnancy rumors.

Drake’s 'Would You Like a Tour?' The money he’s earning on the trek will certainly help pay for the wedding.

Congratulations to CiCi and the Astronaut Kid.
