'Saturday Night Live' promo: Justin Timberlake and Andy Samberg flirt, Lady Gaga appears only in spirit

The 36th season of "Saturday Night Live" is basically guaranteed to go out on a high note, with longtime favorite Justin Timberlake returning for his fourth time as host -- and his 12th appearance.

Lady Gaga will also be in attendance as musical guest and, presumably, some self-parody -- but she doesn't make an appearance in the first promo.

Instead we get a healthy dose of the palpable comedic (and sexual) chemistry between Timberlake and Andy Samberg. In the three vignettes, the duo almost share a kiss, meet their attractive twin sisters and get a visit from the ghost of 30 Rockefeller Plaza. (Impressive graphics!)

Watch the promos below and tune in May 21 for the finale.
