Streep set for '30 Rock' cameo

Alec Baldwin won more than a Screen Actors Guild award last week - Meryl Streep has agreed to appear on his TV hit '30 Rock'.

Streep was delighted after winning a Best Actress nod for her role in 'Doubt' and her good mood continued when Baldwin approached her about guest-starring on the US comedy show, which won three gongs at the prizegiving.
