Blushing: Selena Gomez is overjoyed by surprise meeting with her long-term crush, Shia LeBeouf
He may have millions of adoring fans but Justin Bieber might just be jealous that the one girl he wants to go weak at the knees for him, girlfriend Selena Gomez, has a crush on another star.
The 18-year-old is mad for Transformers star Shia LeBeouf, and she's not afraid to admit it after posting footage of her surprise meeting with the 25-year-old actor on YouTube.
Gomez' friends tricked the Disney star into going to LeBeouf's dressing room on the pretence she was meeting fans.
And despite her fame, Gomez was starstruck and only managed to blurt out 'I'm so sorry to bother you,' before running out of his dressing room.
But action man LeBeouf chased her down and gave her a hug before posing for pictures with the brunette.
'Thanks for being so sweet to me,' Shia told Selena. 'You’re really sweet to me.'

'I admire you,' Selena spluttered, and back in her own dressing room she berated her friends.
'You guys suck! You used my fans as bait!' she said.
'He’s so cute…Oh my gosh, he’s so handsome, I’m so embarrassed.”
Adding, 'Now he thinks I’m crazy!'

Gomez posted her video yesterday and titled it Meeting Shia, with the caption 'best day ever.'
You can only wonder what Bieber thinks about it, as he was today still patiently following his lady on the promotional trail for her new movie and album.
The 17-year-old, who is more used to being the headline act, accompanied Gomez to an early morning appearance on Fox & Friends in Manhattan this morning.
The pop star appeared a little weary though, and stopped for a caffeine fix while on the run.

Trying not to steal the limelight from Selena, Justin dressed down for the occasion in a pair of charcoal jeans and a black t-shirt.
But with his signature red baseball cap perched firmly on his head, there was no doubt the chart-topping singer was present.
Selena looked sensational in a slinky knee-length purple coloured sating frock, which she paired silver pointed toe heels.

The dress accentuated the singer's glowing olive complexion and she wore minimal make-up on her flawless and youthful face.
And while Selena looked all grown up for her promotional appearance, on the show Selena said that she would not be completed ditching her Disney roots.
'I have finished with Disney Channel, but that does not mean that I want to completely disown the fact that I do have a younger generation looking up at me,' she said.
'I feel like I’ve done the best I can. If I make my family proud and if I make my fans proud that’s all that matters to me.'

Supporting each other's careers is just another sign that the couple relationship is getting stronger and closer as days go by.
Last week, even after surviving a reported fan attack at Macy’s Herald Square in New York, Justin made sure to pick himself up and head to Selena’s film premiere.
Bieber there met up his girlfriend to support her at the premiere for Monte Carlo – her new romantic comedy that also stars Leighton Meester and Katie Cassidy.
Days before he also wrapped a protective arm around Selena when she hosted the MuchMusic Video Awards awards ceremony.

The film sees three young women on holiday in Paris and find themselves whisked away to Monte Carlo after one of the girls is mistaken for a British heiress.
Selena stars in the film alongside two of Gossip Girl’s actresses Leighton Meester and Katie Cassidy.
Monte Carlo is set to be released next month, so Selena was keen to promote her new project to her fans.
Selena is currently promoting her hit song 'Who Says' which she performs with her group Selena Gomez and The Scene.
