Actor Bradley Cooper might take his mother to the Oscars instead of his girlfriend Suki Waterhouse.

Attending last year's ceremony with his partner, he's reportedly not yet decided which lady in his life to take this year to the event, taking place Sunday, reports femalefirst.co.uk.

The Sun newspaper reported that friends of Waterhouse were told by the model at a party here: "I don't know if I'm going yet. Bradley needs to decide on his plus-one."

Nominated for the Best Actor award at the gala for his portrayal of navy SEAL Chris Kyle, Cooper was seen taking his mother to the 2013 ceremony where he lost out in the same category to Daniel Day-Lewis.
