DailyEdge.ie rounds up the TV shows that you’ll be tweeting about tonight and talking about tomorrow.

The Late Late Show Valentine’s Special (RTÉ One, 9.35pm)

Are you ready? Because you’d want to be. Once again, RTÉ invites singletons on the Late Late, gives them a few sherries, and lets them run riot. Previous years have been…raucous, to say the least. #latelate

If you can’t handle the Late Late, hop on over to Graham, who has a bevy of stars on with him tonight: Denzel Washington, Whoopi Goldberg, Keanu Reeves AND Jamie Dornan. Phew. #grahamnorton

Anchorman (RTÉ2, 9.35pm)

Relentlessly quotable comedy starring Will Ferrell as the titular 1970s Anchorman, Ron Burgundy. Tons of famous faces co-star, including Christina Applegate, Steve Carell, and Paul Rudd.

Everybody’s talking about: The Crown
