Kim Kardashian dodged questions about her $750,000 gift to boyfriend Kanye West Sunday, as she and sis Khloe left a lunch date at LA French bistro Bagatelle.

The reality star purchased a Aventador LP 700-4 for her rapper beau, who spent his 35th birthday on tour in Ireland with Jay-Z. Of course, Kim flew over for a 'quickie' trip, but jetted back to LA just 24 hours later.

Maybe jet lag was the reason she wasn't in the mood to chat ..
