Andy Cohen Celebrates 51 with 'Best Birthday Present of All' as Bravolebrities Wish Him Happy Birthday

Andy Cohen is having a very good 51st birthday, as he gets to spend it with the "best birthday present of all" while Bravolebrities fro his "Real Housewives" franchises and beyond all send well-wishes his way.

The "Watch What Happens Live" host kicked off his own festivities with an absolutely precious picture of him with baby Benjamin ... and we can't decide who has the bigger smile. His "Housewives" friends quickly filled up the comments section of his post with birthday wishes before taking to their own social media platforms to continue spreading the love.

"I got the best birthday present of all," Cohen captioned his post, to which Kyle Richards agreed, writing, "Oh, yes you did. Cannot get over him. You two are twins."

Teresa Giudice and Dorinda Medley echoed Richards' sentiment, while virtually everyone agreed that Benjamin was precious, adorable and gorgeous. Several celebrities from beyond Bravo chimed in with birthday wishes, too, including Kelly Ripa, Michael Rapaport, Carson Kressley, Marie Osmond and more.

Cohen welcomed Benjamin Allen Cohen into his life on February 4 via a surrogate. He's been gushing about fatherhood ever since, and based on the photographic evidence, he's loving every minute of it.

Aside from hosting "Watch What Happens Live" five nights a week on Bravo, Cohen also remains an executive producer on the massive "Real Housewives" franchise. His influence helped bring a new level of fame and success to almost all of the women who've appeared under the "Housewives" banner, and he continues to support them as guests on his show.

And even thought he sometimes goes in hard on them during those wild reunion specials, his genuine affection and friendship for the women who make up each cast always shines through. Perhaps that's why they send that love back to him.

Of course, no birthday celebration would be complete without some love from Cohen's best friend, Anderson Cooper. He shared his own adorable picture with him holding baby Benjamin, captioning it, "So proud of all you've done, and for you and Baby Benjamin, it's just the beginning!"

But we can't get over that side-eye Benjamin is already giving him. Someone is following in daddy's footsteps very well. He looks ready already to handle all those crazy "Housewives." Check out Benjamin's epic side-eye and all of the birthday love already pouring in below:
