HAPPY BIRTHDAY Jennifer Aniston! 42 today! Wonder if she'll be going wild later and throwing one of 'tree trimming parties' to mark the occasion? In the meantime, though, here's a little birthday treat for her - a nice apology from Heidi Montag...

It was previously reported that Jennifer Aniston had banned Heidi Montag from the premiere of Just Go With It, even though the Hills star appears in the film. In return, Montag called the Friends actress a wanker (we're paraphrasing). Having now realised (via our review) that Aniston was doing her a favour, Montag has apologised, telling UsMagazine.com:

"I read that Jennifer had banned me from the premiere for being too polarizing, but I know now that it wasn't true. It never really made sense to me because Jennifer is such a sweetheart and she even commented before on a red carpet about how interesting and fun it was to have me in the movie.

"I was honored to be a part of such a great movie and I apologize to Jennifer and Sony for this big misunderstanding. Go see the movie this weekend! It's fantastic!"

So why wasn't she at the premiere then?

"I got my invite and I would have loved to be there, but I had to be Los Angeles with my dogs."

Well, she's got a friend for life in Aniston now then. Here's the actress appearing on Chelsea Lately earlier this week with her best mate Norman the dog.
