Hey , I am a usa citizen with a usa Passport And I recently visited the London heathrew To meet My friend on 20th Of April 2012 And fly back on 22nd Of April. I am again planning To flyon 12th Of may To London To meet My friend And his family And flying back on the 14th Of may 2012. My question is Will I be granted entry again without any issues or I won't b allowed since I already visited two three weeks ago. Please assist with any suggestions that can Help me To Travel To London again . Thank you 

Regards
Ayesha

From what you've said I don't see there being an issue.

So they won't say like u Just visited why here again or blah blah :( Just want To make sure there are no issues

I agree with CB, but if you are unsure and don't believe us, then call
Immigration.
