The Queen has officially opened the BBC's new headquarters in central London.
She was treated to a performance from Danny O'Donoghue's band The Script in the Radio 1 Live Lounge.
The revamped BBC Broadcasting House was declared open with an announcement from Her Majesty on BBC Radio 4.
During her walk around the BBC newsroom, the Queen triggered cheers and laughs when she appeared live on TV behind the newsreaders!
The Queen's husband Prince Philip had been due to attend, but he was admitted to hospital on Thursday in a planned visit.
