The 50-year-old musician's last tweet came in late October, just days before his ex, Gwen Stefani, and her fellow Voice coach, Blake Shelton, went public with their relationship, and shortly after rumors surfaced alleging that Rossdale had cheated on Stefani with their children's nanny.

Meanwhile, Shelton has been very open about his fondness for Stefani, even going so far as to push for her return to The Voice next season. Earlier in December, Stefani posted a photo of the country rocker affectionately biting her shoulder.
