R&B singer Ciara has now confirmed this morning rumors about her engagement to 29-year-old rapper Future.

The "Overdose" singer showed off her new 15-carat diamond engagement ring --something similar to Kim Kardashian's ring -- in a selfie on Twitter. But before revealing her sparkly-ring to the world, she tweeted last night, "Today has 2 be like one of the sweetest days of my life! #The BestBirthdayEver."
The 28-year-old songstress gushed about her new man back in August on Kris Jenner's talk show saying:

"You have to make time, because that's where you find your sanity. If you just commit to work every day, every day, all day, you get so lost that you can lose yourself." Adding, "Love is really important to me."

Despite his many kids and baby mama drama, I guess they were really serious about taking their relationship to the next level.

Also, Cici will be celebrating her birthday at the Moet Rose Lounge in Houston tonight.
