Demi Moore has ''given up on men''.

The 'Ghost' star - who previously dated Bruce Willis and Ashton Kutcher - is reportedly ready to call it time on dating and is regretting splitting from her second husband.

A source told RadarOnline.com: ''Demi has pretty much given up on men! She is very single and very lonely right now. After Ashton, Demi feels that she is not going to ever really find that connection again with another man.

''Part of her wishes that she never left Bruce Willis. People try to set her up on dates and such, but she is just kinda over it at this period of her life.''

Most recently, the 52-year-old actress has been linked to 'Pirates of the Caribbean' star Orlando Bloom after the pair were spotted on a yoga date.

An insider shared: ''They are both deeply spiritual characters who love yoga, meditation and new age philosophies. They've both been initiated into spiritual practise Usui Reiki and have started to practise on each other.

''At this stage it's a casual thing, nothing serious and it's not yet exclusive. But they've enjoyed several low-key dates together and the potential is definitely there for something steadier.''
