This is entertainment tonight. In just two days, the biggest stars in the usic world will hit the stage behind me for the grammys. We have super secret intel about beyon beyonces performance. She is pregnant with twins and speaking of secrets and twins how about george and mail clooney . How did they keep that secret . One guy who no longer has to keep his mouth shut, georges they are going to be great. They will be lucky kids. Will you give him advice . We never had twins. We had one at a time. That was presentee. Look, it is going to be a huge challenge. One baby cries, wakes the other one up. Itll be on in that household. Hes not 30. Its tough. Yeah. He doesnt sleep a lot anyway. Hell be all right. Here is the first shot of the barely there baby bump. Amal eight days ago at a conference in barcelona mp in this shot, strategically using a binder to hide her tummy. You did a hell of a job keeping it secret. He didnt tell me to keep it quiet. He told me. I told my wife. Congrattlations. And new that the secret doesnt get out if you dont tell anybody. But george kind of probroke pregnancy rule when he dropped the news to matt last fall on the movie set that clooney is directing. I said how along is she . He is like eight weeks. Im like, are you out of your mind . Dont tell anybody else dont you know the 12week rule . Of course he doesnt. Just shut up, man. Four weeks later, im like, were good, right, were good . Bringing joy little children. This is what a forensic artist imagined the twins would look like if they were a boy and girl. We will wait and see but one thing we know for sure is that 39yearold amal will have thee best pregnancy style. She is always, since the day i et her, she always had this inssnely ecceetric but fun sense of fashion. You had to probably expand the bachelor closet a little bit. You mean for her . To make room. Are you kidding . Yes. Another bedroom,i think. Can we go back to the memes for a second . This has to be my favorite. Georges face photo shopped on beyonces body. Speaking of the real beyonce performing sunday night, i expect to ken you aand he is be coy about what whats for show time. If that happens it will be amazing. We learned beyonces performance may include the singer dressed in gold, pairing on a giant turntable. The theme, beyonces journey and evolution with actresses playing her in different stages of life. But dont look for any highflying acrobatics or over the top stunts. Beyonces pregnancy is considered highrisk due to her age, 35, and the fact she is carrring twins. Wouldnt it be any special ac accommodations made because she is pregnant with twins and her tummy did not look tiny when i saw her. It is not tiny and i saw it last night.
