Neil Patrick Harris

Dr. Horrible's Sing-Along Blog director, Joss Whedon, and Neil Patrick Harris may be making sweet music together yet again.

The How I Met Your Mother Star is nearing a deal to appear in the May sweeps episode of Glee that will be directed by Whedon, Entertainment Weekly reports.

Ryan Murphy, creator of the Golden Globe-winning freshman series, would create a role especially for Harris, which would entail a fair share of singing and dancing. Zachary Woodlee, who choreographed the musical number in HIMYM's 100th episode, would also take part.

A call to Fox was not immediately returned to TVGuide.com.

Do you think NPH would be a good addition?
