Diddy had the bubbly overflowing this past weekend ... but it wasn't a Sunday Funday on the heels of his ex's death anniversary.
Diddy and his crew hit up BBCM on Sunset Blvd. in WeHo on Sunday and guzzled mimosas. It looks like he had a variety of flavors ... evidence the near-empty flutes on his table. He looked somber.
The mimosa fest came just 2 days after the 1-year anniversary of the death of his ex, Kim Porter. He paid a touching tribute to her over the weekend, saying, "I MISS YOU SOOOOOO MUCH. Every time I get sad I look at this video and it brings a smile to my face."
Diddy went on to say, "I thank god for the precious time he allowed us to have with you. I wish you were here with us right now and this was all a dream. I will never give up on that wish. Never!!!! Love you forever Kimberly Antwinette Goodwin Porter."
As we've reported ... Diddy's struggled coping following Kim's sudden death last year. Earlier this year, Diddy broke down in tears reminiscing on their life together.
