Heidi reaches out to Lauren and we did NOT see it coming!

Lauren Conrad was married to William Tell last weekend during what was most definitely a Pinterest perfect wedding.

While no photos of the big day have yet been released by the reality TV star and clothing designer, it is easy to assume that certain Hills alumni not in attendance were Kristin Cavalleri and Heidi Montag.

Well, in an interesting move, Heidi decided to acknowledge the fact she was not at the wedding by congratulating Lauren over Twitter last night.

Heidi tweeted to her old friend: “Congratulations @LaurenConrad on finding true love and your soul mate! Sending you love and blessings! The best is yet to come! Love you.”

So Lauren didn’t invite her old frenemy eh? Interesting given that Lauren came along to see Heidi marry the awful Spencer.

The two ended on a good note surprisingly, with Lauren even coming to see Heidi at the back of the church before she walked up the aisle.

Could it all have been for show…hmm!

We can’t wait to see which of The Hills crowd DID make the invite list! Was Brody Jenner in attendance after skipping out on sister Kim’s wedding to Kanye back in May? Time will tell…
