TMZ has learned that Charlie Sheen went face to face with his estranged wife Denise Richards on Thursday as he sat for his deposition in his divorce case.

Sheen arrived with his lawyer, Lance Spiegel, and Richards showed up alone. The deposition was taken in Beverly Hills at the law offices of Neal Hersh, Richards' lawyer.

We have no details as to what transpired inside the deposition, but once source told TMZ it was a "highly tense situation." The divorce has been bitter, with Richards making various allegations against Sheen, all of which the "Two And A Half Men" star has denied.
