Sean ‘Diddy’ Combs’ Ex, Cassie, Expecting First Child with BF Alex Fine

On Wednesday, Cassie, 32, announced that she was expecting with boyfriend Alex Fine, 26. She wrote 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.”

Along with promising to show his daughter a “healthy relationship,” Alex went on to pledge, “I promise to never approve of any boy you like because they will never be good enough for my baby girl. Sorry I can't promise that I won't embarrass you because I will give you so many kisses at every school drop off. I will be the Dad that never forces my opinions on you. I will love whatever you do in life as long as you're happy.”

Fine ended his letter with, “I promise to love you every single second unconditionally until my last breath. You're perfect to me and always will be.”

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.

The baby news comes just six months after Cassie debuted her beau on Instagram. In December, she posted a kissing pic from her mom's birthday celebration.

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."

Cassie and Sean made their last public appearance together at the 2018 Met Gala.

A year before the breakup, Combs gushed to Wendy Williams, “I'm in love now.”

Over five years ago, Cassie opened up on their relationship, telling Madame Noire, “Just being around him is a completely inspiring experience. The key to maintaining any relationship, be it a romantic relationship or a friendship, is honesty and communication.”
