“I wasn’t familiar that they were taking the trip," the president says in an interview with Today's Savannah Guthrie that was conducted Monday before the Boston Marathon bombings and aired Wednesday on the NBC morning show.

In “Open Letter,” Jay-Z implies Obama reprimanded him directly for touring Havana: “Obama said ‘Chill you’re going to get me impeached’/ You don’t need this sh—anyway, chill with me on the beach.”

For those who were duly impressed by the antics of "master crasher" Vitalii Sediuk--aka, the dude who managed to sneak into this year's Grammy Awards and hop on stage during Adele's trophy acceptance--better not attempt his antics. The Ukranian prankster is currently facing possible jail time as a result of his smooth moves.

The Los Angeles City Attorney has filed charges against Sediuk which could amount to six months jail time plus a $2000 cumulative fine, citing that in this age of "heightened security," anyone who crosses a line as he did will be held fully accountable for his or her actions.

Jessica Simpson was all smiles at her Tom Sawyer-themed baby shower in Los Angeles on Sunday, where the superstar singer/actress/fashion mogul celebrated the imminent arrival of her little one with family and friends.

Simpson’s mom Tina, sister Ashlee, and 11-month old daughter Maxwell Drew were all on hand to join in the festivities, which took place near a pond at Hotel Bel-Air and featured a game where guests fished for party favors including blue nail polish and condoms, because “this baby was a surprise for Jessica and Eric,” as party planner Mindy Weiss pointed out.

The menu included Southern comfort food and a grilled cheese station for kids.

“I’m so excited to have a son,” Simpson told People Magazine. “He got all these cute vintage cars and I got a lot of little leather jackets I can’t wait to try out!”

The curvaceous star indulged in some fried chicken, adding that she’s been working out three times a week with

Just last year, White's solo debut, Blunderbuss, became the best-selling vinyl LP of 2012 by knocking The Beatles' Abbey Road from the top spot with sales of 34,000 copies. Now Jack, who is serving as ambassador of this year's Record Store Day, wants fans to become part of the vinyl revolution by inviting them to his Third Man Record Record Store in Nashville to record themselves on vinyl in his new Third Man Record Booth. It will debut on Saturday, as part of the Record Store Day celebration.

"Certain beautiful experiences can only happen in the environment of a record store and I just thought that nothing could drive that point home more than a one-of-a-kind machine that lets you not only record your own vinyl record, but send it to anyone, anywhere in the world to share a song, poem, or private message with," Jack says in a message posted on the Third Man website.

Normally an album release is cause for celebration. But instead of celebrating, Fall Out Boy has struck a more somber tone, announcing that they'll honor the victims of Monday’s Boston Marathon bombing.

The band announced via their website on Tuesday that they were sending their thoughts and prayers to everyone affected by the bombing, and that they would donate proceeds from their concert at Tsongas Arena in Lowell, MA (about 30 miles from Boston) on September 6 to the victims.

“As you guys all know we’ve been beyond excited for today to come and normally this would be a day of celebration with the release of our new album,” the statement read, referencing the new album Save Rock And Roll, which came out Tuesday.

Tyga is signed to two labels who promote big spending and operating as a family.

But the Young Money/Cash Money recording artist – who released his second Cash Money album, Hotel California, April 9 – said he’s yet to get paid from the label home of Lil Wayne, Nicki Minaj, Drake and others.

"I never got a check from Young Money or Cash Money," Tyga said during an interview April 15 on New York radio station Power 105.1.

The Facebook group Make Ding! Dong the Witch is Dead Number One the Week Thatcher Dies launched shortly after The Iron Lady’s died April 8, and its efforts encouraged 52,605 supporters to download the 51-second song, the shortest ever singer to hit the pop charts.
