6. Jim Carrey and Jenny McCarthy
The wacky rubber-faced comedian and the raunchy Playboy playmate seemed like a match made in comedy heaven - but the laughter died this past April. The pair were able to share the news of the demise of their five year union in 140 characters or less, both announcing the bad news via their respective Twitter feeds. Jenny said, "I'm so grateful for the years Jim and I had together. I will stay committed to Jane (Carrey's daughter) and will always keep Jim as a leading man in my heart." Jim also kept it short and sweet, Tweeting, "I'm grateful 4 the many blessings we've shared and I wish her the very best! S'okay!" Carrey's bouts with depression and Jenny's time spent with the autism advocacy group Generation Rescue (her son Evan is autistic) may have contributed to the end of seemingly happy-go-lucky couple's romance. Jenny later confessed to Oprah Winfrey that, "when it's not fun anymore, you need to start investigating and do an inquiry into the relationship." With Carrey's affection for Jenny's son and McCarthy's love for Jim's daughter and grandson, they're sure to remain friends.
