Last Wednesday, Irish songstress Sinead O'Connor posted an expletive-laden open letter to none other than pop queen Miley Cyrus on her website. O'Connor's letter was a response to Miley's comment in a recent Rolling Stone interview that the music video for her new hit single "Wrecking Ball" drew inspiration from the video for O'Connor's 1990 song "Nothing Compares to U."

O'Connor, 46, criticized the over-sexualization of Cyrus's new image, even warning the 20-year-old that "the music business will ... prostitute you for all you are worth, and cleverly make you think its [sic] what YOU want." Zing! That was a more PG selection of the letter, by the way.

Despite its crass language, the overall tone of the letter was one of care and concern for Cyrus that obviously stems from O'Connor's own experiences with the music business. Showing Cyrus some "tough love" may be the only way to really get her point across. O'Connor even advised Cyrus that she is "worth more than [her] body or [her] sexual appeal."

Miley, however, turned to Twitter to respond, simply tweeting, "Before Amanda Bynes ... there was ..." followed by a picture of O'Connor. Many have taken offense at Cyrus's Twitter response, arguing that it was insensitive toward mental illness, considering that actress Amanda Bynes is currently undergoing psychiatric treatment.

It doesn't stop there. Adding to this media-dubbed "feud," O'Connor has since wrote two more angry open letters to Cyrus and has even threatened legal action against her on account of her emotionally damaging tweets. 

If Miley's recent photo shoot with acclaimed photographer Terry Richardson is any indication-a photo shoot in which she, once again, wears nearly nothing-she certainly isn't heeding O'Connor's seemingly well-intentioned words. 

In other news this week, the rep for Glee's Naya Rivera confirmed on Thursday that the actress is engaged to rapper Big Sean. Rivera, 26, and Big Sean, 25, dated for around six months before their engagement. 

Twitter also plays a role in this bit of pop culture news-Rivera admits that she initially connected with Big Sean through exchanging messages on the social media website. Ah, Twitter-the maker and breaker of Hollywood relationships.

Some more big celebrity news broke late Saturday evening, when media outlets announced that Halle Berry and her husband, French actor Olivier Martinez, welcomed a baby boy. No word on a name at the time of the announcement, but this is the second child for Berry, who had her five-year-old daughter Nala with her ex-boyfriend and Canadian model, Gabriel Aubrey. 

Berry, 47, was previously married to baseball player David Justice, and then to musician Eric Benet. 

Then, in July, she married Martinez. In an interview with CNN in April, she called this second pregnancy "a big surprise." Nonetheless, a big congratulations is in order for the happy couple!

Well, Brandeis, there you have this week in pop culture. We'll wait and see how Twitter might dictate next week's celebrity news.
