Ciara might be on top of the world right now, but it looks like there's a good reason why her ex-fiance Future has been so quiet lately. After he criticized his baby mama for being a bad mother to their son Future Zahir Wilburn, the rapper has said next to nothing thanks to a potential $15 million dollar lawsuit Ciara slapped him with.

Yet, according to Hollywood Life on Saturday, sources close to Future say that he's "happy" for Ciara and her future husband Russell Wilson after the couple announced that they are engaged and set to get married soon. After being so vocal and critical of the two in the past, either Future has had a change of heart or he's secretly freaking out over the news.

"Future's not shocked by this engagement news - that's classic Ciara," one source said. "She falls in love hard and at the drop of a dime. What will shock Future is if she actually elopes because Ciara's known for calling off engagements."

The tipster then went on to add, "But Future wishes her the best."

Yet, the rapper blew up after seeing photos of their son Future with Russell at a NFL training camp and even slamed her on Twitter by sayin, "This bitch got control problems ... I gotta go through lawyers to see baby future ... the f***ery for 15k a month."

So far, Future himself has not made any public comments about Ciara's engagement.
