Justin Bieber reportedly bought every flower in a florist's shop for Selena Gomez.

The 16-year-old singer phoned a store last Wednesday (16.02.11) and asked staff if they could "fill" his rumoured girlfriend's house with bouquets.

The store told the 'Baby' hitmaker they could make it happen and set about creating an epic floral tribute to the 18-year-old Disney star.

According to gossip website TMZ, the shop used every flower in stock and had to use "multiple trucks" to deliver the romantic gift to Selena's house.

A source close to the couple claims the singer-and-actress was "thrilled" with her gift.

Justin was in London most of last week to attend the BRIT Awards - where he took home the prize for International Breakthrough Act on Tuesday night (17.02.11) - and to promote his new documentary movie 'Never Say Never'.

Selena had previously revealed they wouldn't be spending Valentine's Day (14.02.11) together because of work commitments.

She said: "I'm actually going to be working all day, so my Valentine will be my fans."

Neither Justin or Selena have confirmed they are an item but have been rumoured to be dating since January and have been spotted on several dates holding hands.
