Pregnant Cassie Ventura Is Engaged to BF Alex Fine

Over the weekend, Alex popped the question to Cassie in Compton.

Alex posted a pic of himself down on one knee, writing on Instagram, “This moment will always be so special to me. I get to marry my best friend in the whole world. How am I so lucky! #mrsfine.”

In another video, Cassie is seen arriving at a ranch and Alex gets off his horse to propose to her. Alex pulled off the proposal with the help of the Compton Cowboys and Emilio Sanchez.

Cassie also shared a photo after she said 'Yes,” saying, “I love you best friend. I can't wait to spend the rest of my life with you.”

The engagement comes just months after Cassie announced that she was pregnant with Alex's baby.

In June, Cassie revealed that they were expecting a baby girl, writing on Instagram, “Can't wait to meet our baby girl 💗 Love You Always & Forever.”Alex also wrote a sweet letter to his daughter, promising, “I will be the first man in your life and will show you the greatest love and affection now and forever.”

He added, “I never thought my heart could grow bigger after meeting your mother... then I found out we were having you and I instantly felt a love that is so indescribable… I promise to be a man that you and your mother look up to and love. I will always listen and put the both of you first.”

Alex wasn't done there… he also wrote a special letter for Cassie. In his letter of promises, he stressed, “I promise you that I will do every single thing in my power to support you and help you. I promise that you will never be alone. I promise that you will be loved beyond expectation and we will show our children how to be in a healthy relationship. I promise to always come home with a great attitude and give our children and you undivided attention. I promise to always keep you and the child first nothing comes before you. I promise you will be showered in kisses and hugs every single day. I promise that I will be the best father/baby daddy.”

“I cannot wait for the rest of our lives together and to raise a beautiful happy child in our beautiful happy life,” Alex continued.

Alex and Cassie made it Instagram official in December.

Alex is known for training the “Riverdale” cast; Kelly Ripa and Mark Consuelos; and Reggie Bush. When he's not training celebrities, he's a bull rider.

TMZ reported that Cassie and Alex met through her ex, Sean “Diddy” Combs, who had hired him as her personal trainer. They started dating months after her split from Diddy, her on-again, off-again boyfriend of 11 years.

At the time, a source told People magazine, “The decision was amicable and they remain friends. Cassie is going to focus on her music and acting career.”

Her rep confirmed the breakup to LoveBScott, saying, "They are indeed no longer together and haven't been for months."
