Cara Delevingne crushing on singer Heloise?

Model-actress Cara Delevingne is reportedly "obsessed" with singer Heloise Letissier.
The "Paper Towns" star was devastated when she split from St Vincent, aka Annie Clarke, in August, but has now turned her attentions to the French beauty, who performs under the pseudonym Christine and the Queens, reported Grazia magazine.
"Cara was heartbroken when Annie ended their relationship but she's made no secret of her crush on Heloise," a source said.
"She really admires her artistry and thinks she's super-sexy, so I wouldn't be surprised if that ended up developing into something."
It was recently claimed Delevingne and St Vincent - who is now believed to be dating actress Kristen Stewart, ended their 18-month romance because their work kept them apart for long periods of time.
