Honestly, that Rihanna. She may be 24 years of age, but she's got the mood swings of a teenager.

One minute she's all 'look at me and how god damn sexy I am' and the next she's flipping the bird at paps trying to take a nice little picture of her.

RiRi 'did an Adele' as she left swanky LA restaurant Giorgio Baldi last night after jetting in from from Sydney, where she's been promoting her film Battleship.

We would just pass her strop off as jet lag, but it isn't her only diva tantrum of late, as she threw a massive wobbly during a recent interview on an Aussie TV show when they dared to ask about her love life.

Admittedly she's already warned the journalist she wasn't her best, saying: "I'm a little icky... (Last night) I couldn't walk... I went straight to bed."

But things went from bad to worse after the host asked about her reported romance with Ashton Kutcher, as well as bringing up her most hated interview topic, ex-boyfriend Chris Brown.

Asked if she minded all the speculation about her love life, Rihanna snapped, "It's very frustrating, almost as frustrating as being asked about it."

When Barr pressed for more, stating that her fans would be interested, the R&B beauty responded, "They're interested in a lot of things that don't matter - or shouldn't."

Rihanna then signalled for her PR to bring the chat to an abrupt halt.

Awkward.
