That's the father of my child! Blooming Beyoncé cheers on Jay-Z as he performs surprise set at the Victoria's Secret Show

They're hardly the average expectant couple, but no-one could accuse Beyoncé and Jay-Z of not supporting each other.

And though the Victoria's Secret Fashion Show might not be the most tempting destination for many pregnant women, the 30-year-old Run The World star looked only too happy to watch last night.

Beyoncé cheered enthusiastically as her husband performed a surprise set during the flamboyant $12 million New York show.

The rapper was called onstage by Kanye West as an unexpected treat for the delighted crowd.

Kanye asked his 'big bro' to come out, prompting Jay to march onstage to perform a duet with his friend from their Watch the Throne album.

Beyonce looked thrilled, dancing along and grinning ear to ear as her man strutted his stuff.

The star wore an elegant white kaftan over her blooming bump, with her hair falling in loose curls over her shoulders.

And the men weren't looking too shabby themselves, with Kanye sporting a Versace for H&M jacket and Jay-Z rocking his usual black hoodie and gold chain.

Kanye had been due to perform at the show in 2007, but backed out due to the sudden death of his mother Donda West.

He took a moment to remember her before launching into his smash hit Stronger, saying: 'In 2007, I was supposed to perform this song...then my mom passed away. She was my superhero—now she's my superangel.'

Though Beyoncé still looks every inch her usual glamorous self, the singer has admitted that pregnancy is having some strange side effects.

'I don't know if you'd call it weird, but I'm having ketchup with everything,' she told Closer magazine recently.

'I mean, I liked it before I was pregnant, but I now literally won't eat anything without it.

'Breakfast, lunch or dinner - I need to have a bottle of ketchup close to hand.'

She hasn't been too shy to splash out in preparation for her baby daughter, and has already spent thousands of dollars converting around 2,200 square feet of her New York apartment into a nursery.

Since it started 11 years ago, the iconic show's budget has grown considerably - from $120,000 to today's bank-breaking $12m.

A total of 60 costumes were made this year, along with 31 sets of angel wings, worn over the course of the evening by 38 models.

'It's so extravagant this year,' she had cooed earlier.
