Katie Holmes has ignited gossip a new baby is on the way by buying Suri a ‘Big Sister’ T-shirt.

The actress is reported to have spent over £1000 on babywear at LA boutique Petit Tresor last week.

Suri got a new summer wardrobe and Katie also picked out baby clothes.

‘Katie ordered loads of cute girlie spring dresses for Suri,’ a source reveals.

‘But she also bought a pink T-shirt which said Big Sister and two matching rompers suits, one which said Little Sister; the other saying Little Brother.’

In December last year Katie, 29, admitted she’d love more kids with Tom, 45.

‘She had it all figured out,’ the source tells People.

‘She would shoot her new movie and then get pregnant. She was hoping to have the baby by the end of the year, go back to work next spring and have another film out by the end of 2009.

‘Both she and Tom – especially Tom – were hoping to have their next baby before Katie turns 30 in December.’
