All eyes will be on Charlize Theron and Hurt Locker star Jeremy Renner at tonight’s Oscars ceremony.

The pair have been seen together in Tinseltown recently and I’m told they may attend the post-Oscars Vanity Fair party.

Renner’s movie about a US army bomb squad in Iraq is up for several nominations and former Oscar winner Charlize, 34, is due to present one of the awards tonight in Los Angeles.

Having a blast: Charlize Theron has been getting close to Jeremy Renner

‘They get along very well and we suspect something is going on between them, although they are being very coy,’ says a source close to Charlize.

She has been single since calling off her nine-year engagement to Irish actor Stuart Townsend, 37.

Renner, 39, recently revealed he visits Charlize at her home and said: ‘We’re just friends. We’re crazy about each other.

'I can go hang out with her and play her piano and sip Scotch.’

The source added: ‘They’re keeping things below the radar as Charlize doesn’t want to upset Stuart.

'But the fact is she is dating again and Jeremy has been spending a fair amount of time with her.

'They get on well but Charlize is lined up to do Mad Max 4 soon in Australia, so she doesn’t want a serious relationship.’

Unfriendly: Nicole Kidman

Oscars special 2:

Gwyneth Paltrow and Nicole Kidman are set to play lovers in The Danish Girl – but it seems there is not much love lost between them.

The pair have been living within miles of each other in Nashville for weeks – but Nicole, 42, declined an invitation to meet Gwyneth, who is filming Love Don’t Let Me Down.

A Stateside spy says: ‘Nicole lives in Nashville not far from where Gwyneth, 37, has been working on her latest movie for five weeks.

‘Gwyneth made the effort to get in touch with Nicole but Nicole declined. Gwyneth is on her own – it would have been nice for Nicole to make the effort.’

Oscars special 3:

British Oscar hope Carey Mulligan will be quaffing champagne with Hollywood’s glitterati this evening – but she has instructed boyfriend Shia LaBeouf to lay off the booze.

The 24-year-old’s American actor lover has a reputation for hitting the bottle and taking his own alcohol to VIP events.

At the New York premiere of her nominated film An Education, the relatively unknown Mulligan had a ‘lover’s tiff’ with LaBeouf, 23 – who she has been dating since last August.

Laying off the booze: Shia Labeouf and Carey Mulligan

LaBeouf, who will star in Wall Street: Money Never Sleeps, sneaked a bottle of whisky into the event, which he drank alone in a corner of the Brasserie 8 bar.

‘It was very awkward for Carey,’ says my source.

'Shia stayed in the bar drinking whisky all night and not chatting to anyone. It was very unchivalrous and they had a huge row.

'Carey has said that he has to be on his best behaviour and support her at the Oscars – or not to come at all.’
