The Mean Girls star was recently linked to the Scottish actor after she reportedly locked lips with the star at a bash in Morocco, reports the Daily Star. But the 23-year-old denied the rumours on her Twitter page, insisting she would not have the time to keep track of all her rumoured suitors.
She wrote, "One minute I'm dumped, the next I'm dating a model, now Gerard? WHO HAS THE TIME! Such lies - it keeps me laughing."
