In an increasing show of familial affection that would make our own Karan Johar proud, Hollywood actors and actresses are frequently bringing their mothers to the red carpet instead of spouses and lovers.

Here's a quick look at some mamma's boys and then some girls with their moms:

George Clooney

Oscar-winning actor George took his mother Nina to the premiere of his highly acclaimed Up In The Air.

The striking Nina won many a beauty pageant in her time, and continues to look extremely attractive. No surprises where George gets his dazzling looks, eh?

Star of Kathryn Bigelow's Oscar-sweeping Hurt Locker, Oscar-nominee Jeremy Renner took his mother Valerie to the Oscar show.

Renner, at 39, is one of the 'discoveries' of the season and we bet his mother couldn't have been prouder.

Iron Man star Downey Jr took his mother Elise along when he was getting his hands cemented for posterity on Hollywood's Walk Of Fame.

Back when Robert Downey Sr used to make films, Elise acted in several of them.

Now playing Watson to Downey's Holmes, Law took his mother Margaret along to the 2004 Oscar awards, when he was nominated for the film Cold Mountain.

Maggie, like Law's father Peter, was a teacher in South London.

Clearly it's a safe bet to bring Ma out for the Oscars, as is evidenced by this 2008 pic of 'bad boy' Colin with his mother Rita.

A Dublin housewife, Rita was married to Eamon Farrell, a footballer, and has three children other than Colin.

Pictured here with mother Gerda at a film premiere in 2009, Charlize is very close to her mother.

At the age of 15, the young South African witnessed Gerda shoot her father dead, in self-defense. Many years later, Theron won a Best Actress Oscar for playing a serial killer in Monster.

Okay, Kat isn't strictly Hollywood, the tattoo-goddess best known for her work on the hit TV shows Miami Ink and LA Ink, but we decided to make an exception and put her pic out there simply because of her style.

In this 2009 pic, she's seen showing off not just her mother Sylvia but a tattoo of the lady on herself. Nice.

In this candid 2008 snap at the Edinburgh premiere of The Edge Of Love, Knightley is seen alongside her mother Sharman Macdonald, an award-winning playwright.

The occasion is special for both ladies as it marks an occasion Kiera stars in a film written by her mother.

The stunning Beyonce is seen here with mother Tina at a 2008 promotional event.

Tina Knowles is of Creole descent, and was a costume designer and hair stylist when she gave birth to Beyonce and her sister Solange.

Destiny's Child, in fact, initially used to rehearse at Tina's salon.

In this pic from the 2004 Golden Globe Awards, the gorgeous Nicole Kidman is seen with her mother Janelle Ann.

A nursing instructor and member of the Women's Electoral Lobby, Janelle also edits books written by Nicole's father, Dr Anthony Kidman, a biochemist based in Sydney.
